Yeah totally -- I'm a fan of Botch and Old Man Gloom.
I got to see Botch quite a few times way back when (1998 - 1999ish). The new Old Man Gloom stuff is great too ("THE DEAD WILL BE BURRIED CELLOPHANE!").
Way back when just about every band did that stuff with the lights. Dillinger still does it.
Pretty much they just turn off all the lights in the place, and point a whole bunch of strobe lights (the kind you can get just about anywhere) right at the audience. So those bands that swing their instruments around all the time look a little bit cooler doing it.
I saw Botch a pub a few blocks from where I used to live so it was pretty easy to do that, they were opening for a pretty well known local band so hardly anyone knew who they were (that's how I first heard of them when I saw them).
They were great, and I'm really surprised that they hardly got any recognition until after they called it quits.
