In May 1968, the band moved into Pye Studios in London's Marble Arch to record their debut album, "Shades of Deep Purple", which was released in July by American label Tetragrammaton, and in September by UK label EMI. The group had success in North America with a cover of Joe South's "Hush", and by September 1968, the song had reached number 4 on the "Billboard" Hot 100 in the US and number 2 in the Canadian "RPM" chart, pushing the "Shades" LP up to No. 24 on "Billboard"s pop albums chart. The following month, Deep Purple were booked to support Cream on their "Goodbye" tour.
