I think the only opening... Wait, that was the show that the main band never showed up at... I forget if they were opening or replacing the main band, but the only extra I ever really checked out much was Bullets and Octane, I think. They were really out of place at a punk show, but after getting over that, I noticed they had some
catchy tunes, so I gave 'em a shot later on, and came to like their music.
Otherwise, any opening bands I ever checked out at shows were usually from various local shows -- usually bands that were friends with
Soul 4 Sale (who were usually an opening band, themselves -- I think they opened for The Misfits at least once). Let's see... the main ones that come to mind are
makeoutmusic,
You and What Army, and
Buddha Heroes.
I used to go to a bunch of local punk shows with a friend or two back in the day, but other than those, I haven't really been to many concerts, and those I have been to, I haven't really paid much attention to the opening bands.
