When one contemplates the fabled musical vault of Bruce Springsteen, it's easy to imagine something like the warehouse at the end of 'Raiders of the Lost Ark,' except instead of fabled mythic relics, the room is stacked high with old reel-to-reel tapes.

These days, Springsteen's "vault" is probably little more than an iTunes library on his laptop. But that doesn't make it any less legendary. The Boss began tossing out choice cuts from his archives in 1998 with the four-disc 'Tracks' boxed set. The sixty-six songs on that collection were culled from a rumored 200 to 300 possible tunes. More recently, 2010's 'The Promise: The Darkness on the Edge of Town Story' box included a two-disc set of outtakes focused solely on the sessions for the 'Darkness on the Edge of Town' album.

Similar projects for 'The River' and 'Born in the U.S.A.' are both heavily rumored and high atop the wish lists of most Springsteen fans. The most recent Springsteen album, 'High Hopes,' is even an archival project of sorts; many of the tracks date from sessions as far back as 2002.

With all these archival releases, what's left in that vault of his? Probably tons of material we know nothing about...and at least ten unquestionably classic Springsteen cuts. With the E Street Band now enshrined in the Rock and Roll Hall of Fame, let's take a look at their finest unheard moments on the cream of the unreleased Springsteen crop. With his recent penchant for live obscurities, some lucky audience may even hear one of these in the weeks to come.
