Trees (that's what we're going to be calling them) headlined a show with a couple guests and locals Adai at Monkey Mania, 2126 Arapahoe St. It's a small venue with a back room stage elevated by a couple wooden pallets. There's a chair smashed through the back wall now, wall paneling fallen out into the garage and so much graffiti that it's probably load-bearing. For a hip-hop show, you can usually fit on the stage. Trees and company, crowded out by equipment, had to play on the floor. On tap? Beer. One variety straight from the keg, and nobody seemed to remember what it was. Punks and skinny scene kids tried to be more politically radical than one another to pass time in the bathroom line while burnout metalheads watched indie rock kids tag the walls of the garage.

Trees plays a style of metal and punk called grindcore - it's an uncompromisingly ugly sound that rattles the senses with a hellish racket of rapid fire drumming, jagged melodies and nonstop growls and shrieks - like a soundtrack to a car crash. It's not for everybody, but adventurous listeners looking to bludgeon all their conscious thought half to death will find something to like. Why make beer do all the work?

Openers Adai were the odd man out in the scream-heavy show. The duo cranks out a frightening amount of noise for just a guitar, drums and some pre-recorded effects. But rather than hammering their way past the eardrums, Adai meander and cultivate something massive and stony that you can really get lost in. Check them out in video here.

They'll be back in town April 13 after a tour through the midwest. The next Trees show is scheduled for May 16 after a tour down the West coast.
