The band gained some much-needed publicity in September 1969 with the "Concerto for Group and Orchestra", a three-movement epic composed by Lord as a solo project and performed by the band at the Royal Albert Hall in London with the Royal Philharmonic Orchestra, conducted by Malcolm Arnold. Alongside "Days of Future Passed" by the Moody Blues and "Five Bridges" by the Nice, it was one of the first collaborations between a rock band and an orchestra. This live album became their first release with any kind of chart success in the UK. Gillan and Blackmore were less than happy at the band being tagged as "a group who played with orchestras", both feeling that the "Concerto" was a distraction that would get in the way of developing their desired hard-rocking style. Lord acknowledged that while the band members were not keen on the project going in, at the end of the performance "you could have put the five smiles together and spanned the Thames." Lord would also write the "Gemini Suite", another orchestra/group collaboration in the same vein, for the band in late 1970. In 1975, Blackmore stated that he thought the "Concerto for Group and Orchestra" wasn't bad but the "Gemini Suite" was horrible and very disjointed. Roger Glover later claimed Jon Lord had appeared to be the leader of the band in the early years.
