With Sting on lead vocals and bass guitar, Padovani on lead guitar and Copeland doubling on rhythm guitar as well as drums, the Police recorded in February 1977 their first single "Fall Out" b/w "Nothing Achieving" which the band released on 1 May 1977. However, Sting was dissatisfied with Padovani's technical abilities, paving the way for Andy Summers, whom they met after a brief tour as part of Mike Howlett's band Strontium 90. For a brief period between July and August 1977, the Police performed as a four-piece with Padovani and Summers sharing guitar duties. Having insisted from the start that he wanted to be the sole guitarist for the band, Summers was unhappy with the situation. Padovani himself felt that the disparity in technical ability between the two of them made this an awkward lineup. The night after an aborted studio session with former Velvet Underground multi-instrumentalist John Cale in the producer's chair, Copeland called Padovani and asked him to leave the band.
