A few months ago Austin based experimental collective Thousand Foot Whale Claw released their last album Black Hole Party. Bands that could named experimental are very seldom and hard to find. I think it is not popular or the basis for a big career if you don't write song that are compatible to radio stations. TFWC are more a band that is working on a sound than looking for charts. Their songs are seldom shorter than five minutes and you can't fix them on any theme. Sometimes they go the electronic alley and sometimes like in Genesis Effect the start with an acoustic guitar as a basis for electric guitar excursions. A band a record I often played at my house.
