BBC Four Sessions

In 1908, the French banker and philanthropist Albert Kahn launched one of the most ambitious projects in the history of photography. A pacifist, internationalist and utopian idealist, Kahn decided to use his private fortune to improve understanding between the nations of the world. To this end, he created what he called his Archive of the Planet. For the next two decades, he dispatched professional photographers to document the everyday lives of people in more than 50 countries all around the world. Kahn's wealth enabled him to supply his photographers with the most advanced camera technology available. They used the autochrome - the first user-friendly camera system capable of producing true-colour photographs. Some of the most important of all the 72,000 colour images in Kahn's Archive were shot during three separate visits (in 1908, 1912 and 1926) to Japan. As an international financier, Kahn had established a network of contacts that included some of the most prominent members of Japan's business, banking and political elites. Consequently, Kahn's photographers were granted privileged access to places that would have otherwise been off limits - including some of the royal palaces, where they shot colour portraits of the princes and princesses from Japan's Imperial family. But some of their most fascinating images capture moments from the lives of ordinary Japanese people at work and play. This film showcases Kahn's treasury of films and autochromes of silk-farmers, Shinto monks, schoolchildren, porcelain merchants, Kabuki stars and geishas - pictures that were recorded at a time when this fascinating country was going through momentous changes

BBC Four celebrates merry midwinter in unique style, with an exhilarating blend of folk tradition and burlesque fun. Energetic 11-piece Bellowhead and Mercury-nominated alternative folkies The Unthanks get together with the impressive young singers Thea Gilmore and Lisa Knapp, plus other special guests. Steered by genial host Paul Sartin, the assembled artists perform seasonal songs of their own alongside yuletide favourites, ranging from folk ballads and carols to parlour songs and carousing dance numbers, with everyone coming together for a final knees-up. Filmed at the atmospheric Shoreditch Town Hall, the setting evokes an old music hall combined with a festive Victorian family parlour, bedecked with garlands, period lamps and fireplace. Even the audience are dressed up in old-fashioned finery and prove themselves ready to kick up their heels.

Highlights of a unique gathering of eclectic artists at Air Studios in London to celebrate the songs and composers of the Great American Songbook. Paolo Nutini sings the classic composition Nature Boy, popularised by Nat King Cole, and has fun with the songs of Louis Prima. Melody Gardot enigmatically explores the songbooks of Cole Porter and Harold Arlen, while Claire Martin swings it and performs classic songs by Rogers and Hart and Irving Berlin. Sharleen Spiteri presents her accomplished interpretation of the Billie Holiday classic God Bless the Child and Gwyneth Herbert reinterprets the Walter Donaldson and Gus Kahn classic Love Me or Leave Me with loops and beats. Jose James delivers a smooth and swinging version of Just Squeeze Me, a song made popular by Duke Ellington, while Krystle Warren performs a bluesy version of Cole Porter's risque Love for Sale and a string-laden performance of A Nightingale Sang in Berkeley Square. The session is a celebration of the music and popular songs of the famous and prolific American composers of the 1920s and onwards. Composers such as Cole Porter, Irving Berlin, Johnny Mercer, Harold Arlen, Rogers and Hammerstein and Hoagy Carmichael, to name but a few - composers who wrote the tunes of Broadway theatre and Hollywood musicals that earned enduring popularity before the dawning of rock n roll. These songwriters have penned songs which have entered the general consciousness and which are now best described as standards - tunes which every musician and singer aspires to include in their repertoire, such as Over the Rainbow, Cheek to Cheek, Love for Sale, Love Me or Leave Me, Get Out of Town and The Lady Is A Tramp.

An all-star cast celebrates the influence of reggae on the UK's music and culture in a live concert coinciding with BBC Four's Reggae Britannia documentary season. Expect to hear hits from the 1960s to the present day telling the story of the musical evolution from ska, through rocksteady, roots, dub, lovers rock and beyond. Music director Dennis Bovell assembles a big band featuring some of the most important reggae musicians in the British scene to back up a star cast of singers and toasters including Big Youth, Ken Boothe, Neville Staple, Ali Campbell, Dave Barker, Brinsley Forde, Dennis Alcapone and Winston Reedy, Pauline Black, Janet Kay, Carroll Thompson and Rico Rodriguez. The concert celebrates the journey that captured the turmoil and channelled the dreams of Jamaicans who came to Britain, those who were born here and the white kids who grew up alongside them and embraced their culture and their roots.

In 1973, an album was released that against all odds and expectations went to the top of the UK charts. The fact the album launched a record label that became one of the most recognisable brand names in the world (Virgin), formed the soundtrack to one of the biggest movies of the decade (The Exorcist), became the biggest selling instrumental album of all time, would eventually go on to sell over 16 million copies and was performed almost single-handedly by a 19-year-old makes the story all the more incredible. That album was Tubular Bells, and the young and painfully shy musician was Mike Oldfield. This documentary features contributions from Sir Richard Branson, Danny Boyle, Mike's family and the original engineers of the Tubular Bells album among others. The spine of the film is an extended interview with Mike himself, where he takes us through the events that led to him writing Tubular Bells - growing up with a mother with severe mental health problems; the refuge he sought in music as a child, with talent that led to him playing in folk clubs aged 12 and signing with his sister's folk group at only 15; his frightening experience of taking LSD at 16; and finally arriving at the Manor Recording Studios as a young session musician where he gave a demo tape to a recording engineer who passed it along to young entrepreneur Richard Branson. After the album's huge success, Mike retreated to a Hereford hilltop, shunned public life and became a recluse until he took part in a controversial therapy which changed his life. In 2012 Mike captured the public's imagination once again when he was asked to perform at the London Olympic Opening Ceremony, where Tubular Bells was the soundtrack to 20 minutes of the one-hour ceremony. Filmed on location at his home recording studio in Nassau, Mike also plays the multiple instruments of Tubular Bells and shows how the groundbreaking piece of music was put together.

The definitive documentary record of one of Jimi Hendrix's most celebrated performances, now digitally remastered and featuring footage never seen on television before. It includes such signature songs as Purple Haze, Voodoo Child (Slight Return) and his rendition of the Star Spangled Banner, as well as interviews with Woodstock promoter Michael Lang and Hendrix band members Mitch Mitchell, Billy Cox, Larry Lee and Juma Sultan among others.

Marvin Gaye is one of the great and enduring figures of soul music, but his life was one of sexual confusion, bittersweet success and ultimately death by the hand of his own father. Through Marvin's own words and intimate memories gathered from rare film and recordings, director Jeremy Marre tells the story of a 'life of outer grace and inner torment'. Including interviews with the singer's family, friends and musical colleagues, with re-enactments and archive film of Marvin on stage, at home and in the recording studio.
