“Grown men playing with adult weapons and sophistication galvanized Franklin’s Mast’s young Black singer/drummer Bevis Griffin,” led off the second chapter of Tim Stegall’s “Austin Punk Chronicles.” Published in these pages on the precipice of the pandemic, January 2020, “Glam Punks of 70s Austin Get Up to Their Gypsy Tricks” dusted off the Texas state capital’s barely documented transition between classic rock to punk and beyond. Pivotal to that moment, our town’s seminal constant, Griffin, continues pinpointing a singular moment in music evolution. Author Gene Fowler elicits stories, history, and inspiration starting at 2pm.– Raoul Hernandez
