Bands I wish I got to see perform live but never will now: Motörhead, Black Flag with Henry Rollins, Sonic Youth, Dio, Neurosis (Technically they haven’t disbanded but with Scott Kelly getting kicked out of their ranks, the future looks grim.), Gwar with Oderus Urungus, Soundgarden, Type O Negative, Fear Factory with their classic lineup, and Fantômas seems unlikely to tour again.
Don't let others say that to you. All my friends and teachers think I can do it.
