I wore a Bone Fone hiking in the mountains on acid playing Four Seasons (Vivaldi). It was exsquisite, yet didn't disturb the wildlife. But that was early 70's acid that actually worked, unlike the crap today, so maybe it did sound like Charlie Brown's teacher. Naw, it sounded good other times, too, that's just the one that stands out. Or maybe not...I ate a lot of acid then, and can't remember a time that i wore the set and wasn't frying.
