A lot of bands have signature moves. You know the move You could expect to see every time You see them. Angus Young's guitar spasm duck walk is an excellent example. I know every time I have seen them he's done it that and dropped his pants by the audience's request. There are others Jimi Hendrix was famous for using his teeth to pick that and setting his guitar on fire. That hurt Jimi pretty bad so he didn't do it as much so it can't really be called a signature move. This video has some more moves. How many have You seen live?
