Bruce Springsteen isn’t the only musician to complete or launch anticipated album projects, then to see it never see the light of day. Springsteen is releasing the “Tracks II: The Lost Albums” box set with reams of so-called lost music on Friday. There are many reasons for albums to be abandoned. Those include perfectionist or easily distracted artists, nervous record executives, and sometimes material that is literally lost. Dr. Dre, the Beach Boys, Prince, Green Day, Neil Young and others all had their stories. But as Springsteen notes in explaining while one of discs was dropped: “I always put them away, but I don’t throw them away.”
