The band's management organized the spare time from the UK tour to record new songs for a third album over the course of February and March 1969 at De Lane Lea Studios, with Lawrence as producer and Barry Ainsworth as sound engineer. The pressure of the multiple engagements left the band very little time for composition and most of the tracks were written and rehearsed in the studio. "Deep Purple" was the band's third album to be recorded, even though they had been together for less than one year. According to Nick Simper: "Recording was always a problem. We were always short of material, purely because of our schedule. The fact that we were always being chased by Tetragrammaton for material, we never had the luxury like most bands do now of saying, 'hang on fellas, we need a little bit of down time to just think about stuff and try and be creative.'" Added Blackmore: "That really bugs me...going to the studio, 'right, you gotta turn out an LP, boys.' You know, 'here we go, you gotta write a song..."today".' It’s just ridiculous."
