Portland’s psychedelic instrumental rock outfit Grails‘ new CD Burning Off Impurities, will be out on April 24 on Temporary Residence, in the meanwhile Important Records has the previously released Black Tar FrequenciesEP’s compiled onto a CD. The name of this gem fits the music very well, because most of the album is dark & fuzzy, or should I say downright “nocturnal”.

Grails’ sound is a sludgy noisy version of krautrock molded into dense freeform compositions with a brooding reverby atmosphere, but there are some acoustic pieces as well. I love the oriental riff on “Belgian Wake-up Drill” and I played it on the radioshow a few weeks ago and have been hoping to feature Grails since then. Check out the new tracks from their upcoming album on their Myspace.
