There's the REO Speedwagon 'Box Set Series,' a four-disc collection including many of their best-loved songs -- along with a tasty unreleased track that finds Kevin Cronin taking over the mic in the studio for ‘Ridin’ the Storm Out.’ There's ‘A Matter of Trust: A Bridge to Russia,’ an expanded two-CD/DVD set that combines Billy Joel's long-out-of-print 1987 live album ‘Kohuept’ with 11 previously unreleased songs.

There's the four-disc 'True To The Blues,' which chronicles Johnny Winter's incredible career through 56 tracks from 27 albums -- including previously unreleased performances like ‘Prodigal Son’ from 1970's Atlanta Pop Festival. And the 25th anniversary CD/DVD box set celebrating Roy Orbison's posthumous triumph 'Mystery Girl,' featuring previously unreleased demos, music videos and a new one-hour documentary.

Finally, the winner of this gigantic prize package will have a chance to dig deeper into the too-short but deeply influential career of guitarist Mike Bloomfield via ‘From His Head to His Heart to His Hands.’ The three-CD/DVD set features all of his best solo work, along with choice sides featuring Bob Dylan, Muddy Waters and Janis Joplin.
