A KISS fanatic wows the guys with his over-the-top collection, and Rockology customers surprise the guys on many levels with Taylor Swift, R.E.M. and Michael Jackson pieces that may be too big to pass up.

It's all about Elvis, Johnny Cash, Jason Aldean, Brad Paisley and Rascal Flatts when the guys track down several pieces of rock 'n' roll gold in this must-see episode.

Rare relics from Pink Floyd and Paul McCartney are sure to blow the guys of Rockology away.

Rockology makes a trip to Los Angeles to check out a very personal Guns N' Roses collection, meet with the queen of the groupies and dive into an intense negotiation on high-dollar rock 'n' roll T-shirts.

A rare Nirvana poster's price and significance put Robert and Stephen at odds, while a music executive's mass collection leaves them almost speechless.

The devil is in the details as the guys check out a lead on a Lynyrd Skynrd poster and an Elvis piece that may force them to leave empty-handed.

Set lists from the Boss, wardrobe from Tommy Lee and Beatles candy. The possibilities are endless as Rockology checks out two unique rock 'n' roll collections.

It's all about music diversity as the guys check out items from Porter Wagoner, Hank Williams Jr., AC/DC, Brue Springsteen and Elvis to invest in for Rockology.
