He was their drummer for 29 years. He just started playing too loud one day? Also, Daltrey actually mentions the sound guy.
Zak Starkey likely didn't just start playing too loud one day after 29 years. Instead, the drums might not have been miked properly at that show.
I've seen too many bands end themselves by not reigning in the drummer by putting him on earbuds or earmuffs and increasing the signal to them if he got too loud. Without that control, the guitarist and bassist increase their volume, and since the singer's microphone input can't be opened up without initiating a feedback loop, the singer ends up screaming.
"Cookie Monster Music" might sell to death metal audiences but regular singers don't last long if they're screaming into a microphone.
Daltry is back tracking. He originally blamed Zac. Zac plays electric drums and any fault would be on the sound engineer.
They brought him back only to screw him around 2 weeks later. Now Daltry is still pretending it wasn’t him. This is all on Daltry being a prima donna.
