Sunday night was Technician and Dysrhythmia at the Pontiac, and I’m really glad these guys are from Philly so I have plenty of chances to see them. Dysrhythmia: Complicated, technical mix of math rock, metal, punk, jazz and prog. Sounds unlike anyone else. Technician: Often compared to Shellac. Very stripped down, winding and unpredictable song structures. They’re touring together this fall, so check ’em out if they come to your town.
