I had a gig last night that was amazing challenging - not from the music but from being sleepy. Friday bar gigs are difficulty anyways - work my day job, play with the kids, and head out to a bar starting at 9:30-ish. I usually grab some coffee on the drive to the gig. It can be difficult but during the show - everything work well. Last night - the sleep kept coming HARD. If I happened to close my eyes to listen to the other players - I swear I was starting to dose off - Standing at a LOUD rock gig, holding my Million dollar sax. I was so tired - I left my horn at the bar. I only went one block - quick U-turn and horn was in hand. Weird GIG.
