 On the first of August 1968, Deep Purple entered De Lane Lea Studios in Kingsway, London, with producer Derek Lawrence and sound engineer Brian Aintsworth, who had both worked on their previous album. Tetragrammaton's advance of $ 250,000 had been used to book two weeks in the studio, a time which covered songwriting, rehearsals and recording sessions. Time was granted in larger amount than for the making of Shades of Deep Purple in May, feeding the band ’ s ambition of coming up with better original material than their previous effort.
