Although substantially re-recorded and presented as a new collection, these 12 tracks are odds and ends, “leftovers” from other sessions and new versions of songs that have taken different forms on the road. Springsteen has always written a lot of material which he shapes and filters, with some songs – ones that many fans consider classics – discarded from his sets as he goes. Previously, these sorts of rejects have surfaced on compilations, notably the excellent Tracks box set from 1998.
