A wealth of previously unreleased and rare material can be found on reissues of the early U2 albums "Boy," "War" and "October," due this week via Universal. Each album will be available as a remastered single CD, a deluxe set with a second disc of extras and on vinyl.

U2's 1980 debut album, "Boy," features the previously unreleased tracks "Speed of Life," "Saturday Night" and "Cartoon World" and a previously unreleased mix of "I Will Follow." "Boy-Girl" and "11 O'Clock Tick Tock" are captured in live versions taped at London's Marquee.

The new edition of 1981's "October" boasts a series of tracks taped live at London's Hammersmith Palais and Boston's Paradise Theatre, a BBC session with Richard Skinner and Common Ground's remix of "Tomorrow."

1983's "War" is bolstered here with the previously unreleased track "Angels Too Tied to the Ground," several remixes of "New Year's Day" and "Two Hearts Beat as One" plus the 7-inch single edit of "New Year's Day."
