Lots of great new harsh noise as of recent, and it's hard to recall everything, but here's a short list:
-Anything Chris Conroy-related, including Vat, Unpenis, and Slave Coordination. He also runs the excellent Everything as Dung label. He's a master of producing some of the roughest, nasty sounding "trash harsh noise". For lovers of corroded, blasting sounds.
-Kiran Arora, formerly of Los Angeles, CA, and now living in Austin, TX. I had the pleasure of sharing a few bills with him last week on a short Texas tour and it was a treat to watch him perform every night. Sometimes blown-out 4 track harsh noise and sometimes harsh guitar noise a la Solmania, but more full-force and straight ahead. His tape that came out on Presh a few years back is highly recommended if you can manage to find a copy, otherwise, stay tuned for a tape on Skeleton Dust eventually.
-Have also been enjoying the output coming out of the Team Boro Tapes camp...liked all of the recent tapes I've heard, but the VMS Elit "Destruction Derby" tape really hit the spot, as well as the various Schakalens Bror tapes released on the label. According to the label owner, the guy behind SB isn't really a harsh head by any means, which makes the ripping guitar noise on the tapes that much more endearing.
