Worst absolute quality: A low budget family touring band with a van towing their equipment in a rusty old pickup truck trailer. I attended in a local church for community support. The matron/mother weighed about 400 pounds, had a home haircut, and wore a sheet as a dress. Oh, you meant worst mainstream concerts…
Worst personal experience: Attending Steel Pulse (reggae) with the flu. I looked like a corpse and felt like one too, but got a free ticket. Great music though. I had a laugh from the the huge “Say No To Drugs” banner behind the stage as the crowd lit up everywhere across theater (it’s REGGAE!). Oh, you meant worst on a musical basis…
Most disappointing headliner: Joe Satriani on the 2018 G3 tour. My enjoyment declined as the show went on. Phil Collen (Def Leppard) played super technical blues with Delta Deep. John Petrucci played ultra-precise technical metal songs. Joe Satriani hammed it up with short repetitious technical riffs (not songs per se) over and over and over–with a weak imitation of ‘rock star’ moves. And then he brought out his stainless steel billion-angry-mosquitoes guitar. As it shrieked far above the musical tone range I said to myself “That man has lost his high range hearing.” Two out of three were great.
