Looking at tours / one of gigs etc around London mid May any of the following could quite easilly play EITS ATP:
Mogwai - Playing London Monday before ATP
Bill Callahan/ Smog - Playing London Wednesday Before ATP
Xiu Xiu - Playing London Monday After ATP
Spiritualized - Playing London Tuesday after ATP
and of cause there is all the BSS spin off's / Side projects inc. Fiest.
Anyone think of any others?
