Title says it all... What is the longest set you've played? I think I want to add what is the Longest show you've played as well? I am in a jam band. We don't stop between songs, we don't talk at anytime during a show, and we don't take breaks. This last summer is my answer for both of the questions. Our opening band's bassist got called away for an emergency at the last minute, so I sat in with them for their 2 hour set. Then there was a 30 minute change over to my band. We started at 10pm. We finished at 3am. At the end of the show, my hands were swollen and it was difficult to move my wrists. If our drummers weren't so worn out, we probably would have continued to play... So there it is.. My longest set was 5 hours. My longest show was 7 hours..
