muse isnt exactly hardcore. but i dont know how anyone could just stand still through most of their songs. and patriot center has a 10,000 capacity, if you want personal space you get seat tickets or stay toward the back of the floor.
and yeah, muse had the better part of the show effects wise, but i actually like silversun pickups music more. they sounded great live. i felt kind of bad for them though, because not many people actually knew their songs. they didnt get any love until panic switch and lazy eye which they played last.
