Van Halen 11 times along with a host of other hard rock/heavy metal and pop shows. My friends and I back in the early 80’s all had a defacto competition to see who could put together the loudest car stereo. I know all of these factors have contributed to my hearing loss. Not serious but definitely noticeable, especially in noisy restaurants and bars.
Grace Slick and the Jefferson Airplane at the old Iowa Fieldhouse in 1969. My date and I were second row, center. Grace really didn’t need amplification. MG, she was LOUD !
