So I'm a Frank Zappa fan if you didn't know already...and I really can't get enough of the 1984 Stony Brook concerts. You can find them on YouTube. Sure the songs and electronic instruments sound really dated, but I really enjoy the music itself. My absolute favorite guitar solos are on "City of Tiny Lights" and "The Black Page."
(NOTE: Zappa's lyrics were super PG-13 rated stuff, maybe even R in terms of themes & language...take caution before proceeding!)
