When it comes to German progressive hard rock based on the Deep Purple formula, none were better than Birth Control! The music was grounded in jazz-rock with rock influences. After some years they had found their own, heavy guitar and organ based sound. "Hoodoo Man" was released in January 1973 and contained 6 tracks that refined their sound even more. This was a brilliant album with very confident guitar and organ riffs and interplay. Noske's voice had improved (he became one of the best German male vocalists) and he also drummed better than ever. The key tracks this time were the classic 10-minute "Gamma Ray" (a live favourite), "Buy!" (7:10) and "Get Down To Your Fate" (7:56).
