Avant-metal guitar hero Mick Barr removes everything but the organ track and a few of Yoshiko Ohara's screams, creating a sky-melting version of Bloody Panda's "Grey" for Summon: Invocation, a 13-song remix collection "reimagining" the Krallice-associated funeral doom crew's 2o09 album, Summon. The compilation, out November 15 via the band, also features BP remixes by Matmos, Jarboe, Australian death metal surrealists Portal, and Wolves in the Throne Room/Sunn O))) collaborator Jessika Kenney, among others.
