Knock Knock' is the third studio album by the German electronic musician. Like all DJ Koze records, 'Knock Knock' exists outside of trend and influence. In fact, it's a step further beyond: absolutely every single thing here, from grooves to voices to handclaps, is otherworldly and unique. Which is not to say it is utterly alien abstraction, mind. There is still disco, there is still soul, there is still techno, there is still hip hop, there is still psychedelia - there are even wafts of easy listening, lost crackly thriftstore record memories and, sort of, indie rock - but though it may sound familiar, it never does what your brain thinks it's going to do.
