The Cat Box Quartet was a loose collective centered around Marc Kellaway and specializing in friendly, melodic electronics with or without vocals.

The name dates back to 2002, where Marc decided to split his output into two projects; Exquisite Russian Brides for the droney, noisy, semi-abstract stuff, and The Cat Box Quartet for the things more resembling a form of pop music. The roots of the muisc lis as far back as 1999, where he used the name Mox as all-round label for his output.

Currently The Cat Box Quartet are sleeping, as Marc's more pop-driven electronic works at the moment gets channeled into Boy on Boy and his work as Dorothy Parker.

Besides two EP's and a full length on The Cat Box Corp, an album came out in 2005 on the American label Radio Khartoum.
