Brighton-based 11-piece-funk-powerhouse The Impellers return with a hard-hitting double-sider. "The Knock Knock" is an authentic piece of heavy soul, spotlighting the gritty vocals of lead singer 'Lady' Clair Witcher, while the band busts loose on an instrumental take of the Kaiser Chiefs classic on the flip side, not available on any other format. A very apt 7inch to celebrate Mocambo Records' forty five #30. Tracklisting 1. The Knock Knock 2. I Predict A Riot
