What does "psychedelic rock" mean to you?

To the Pink Snowflakes, it means deafening guitar feedback over head-nod tempo folk songs with "trippy" echo guitar effects and use of EBow note sustainer. It means songs come out of speakers like a wash, at firehose force and with narcotic pacing.

Their set was fun, but so loud that you had to either jump right in or not mess around with it at all.

The Snowflakes decorated their sound with electric violin, the Stockhouse stage with a black-light poster of a unicorn, and the air surrounding their 200+ audience with bubbles streaming from two machines. They played GMF last year, and their set was slightly better today- the songs sounded tighter. Most of their appeal is in the look and feel: the bubbles are whimsical, the band looks like a hobo version of arena-psych-pop band The Flaming Lips, and- if you're into "heavy" things- the noise from the guitar and drums hurts so good.

GMF will change you: the BBQ man's smoke wafts over the fence and gets into your clothes, the sun bakes your skin, and the Pink Snowflakes make you go deaf.

Off I go to watch The Hands and Aqueduct!
