Rumors, myths, contradictions
- Some say he built homemade distortion devices from salvaged radio parts.
- A persistent rumor claims one of his guitars had missing frets or damaged markers.
- One account has him leaving the band before the last known concert; another puts him on stage at the very end.
- An unlikely story says he later played in a wedding band under another surname.
Notes
Compared with Suchy, Birek remains less romanticized. He tends to appear in memory as the practical one: soldering, carrying gear, arguing about sound, keeping things barely functional.
Several people remembered the noise. Fewer remembered the man producing it.
