And while I'm here - put me down for "both" when it comes to the number of people on a stage. I really like large configurations because of the arrangement options they provide. The E Street band would not have been nearly as interesting as a 4 piece. And I thought the arrangements of Leonard Cohen's songs on his Live in London DVD were excellent, as I believe I've said before. His was certainly a crowded stage. On the other hand, I've always thought that the truest test of a songwriter was the ability of the song to be played in a solo configuration, with just one voice and one instrument. Some of my favorite concerts have been solo shows. I think the format I like the least is the power trio. It seems self indulgent - as if to say, "See how much sound we can generate with only 3 of us!".
