Not selling as many records as they had hoped, Steamhammer nevertheless became a top European open-air attraction, mainly due to their excellent live performance. For over two hours each night they would provide instrumental improvisations, exemplarised by the guitar work of Martin Pugh and the harmonica of Kieran White. In summer 1969, Martin Quittenton left the band, followed by drummer Michael Rushton. They were replaced by Steve Jolliffe (saxophone, flute) and Mick Bradley (drums).
Jollife's feel for precise arrangements and jazz influences especially inspired the recording of this second Mk II album. Going beyond the boundaries of traditional blues forms, the band members applied their musical creativity and imagination without the need for technical trickery.
