Trivia Hint #1

While I suffer through a bout of writer's block, I'm going to introduce the first of a series of hints to the trivia answers:

The first two of the 11 answers share one of their two bands in common, and although they both are credited with appearing on many of the same compilations, they never played together in that band. Also, one of these two shares a birthday with me, although he's a bit older.

By first two, I mean the first two revealed in my chronological list.
