Last night The Exploratorium in San Francisco hosted a listening party for the new Residents album, The Ghost of Hope. While it was known the group itself would participate, all indications were that their presence would be minimal, adding some texture to the album as it played.
As it turned out, those crazy wacky Residents flipped the tables on everyone, and instead played along to only minimal backing tracks, creating what could more properly be considered a full performance, closer to how they toured Icky Flix in 2001.
