All Music Guide-"The crazed ‘Exit 9’ now stands as a landmark of Texas psychedelia"

Andy Babiuk of The Chesterfield Kings-"Thanks for making such a freakin’ great record-- Holy crap! It was mind-bending!"

Shindig Magazine- “It ends with some creepy vocal intonations and a crashing fuzz- toned power chord that'll make you wanna go right back and play it again.”

Andy Brown- “Exit 9 is one of those records that burrows itself in your brain on first exposure and doesn’t strike with any less impact on any subsequent listenings.”

Lenny Kaye- “The kind of raw blast that gives garage its primal overdrive, from a band all too deserving of enshrining in the Nuggets hall of infamy...”

3. Vancouver, BC's The Heard consists of Zach W., Kevarnold, Mac Hunter, Pat Binns, Shay Faded, Kaboom, Cons, and many many more, playing music like a wet dream on acid featuring all of your best friends and childhood crushes.
