He composed a few songs for Smokey Robinson, and one of his compositions, Pilot Error, sung by Stephanie Mills, had some success in the dance charts in 1983.

At the beginning of the 80s, he founded the group Cock Robin with Anna LaCazio, Clive Wright and Lou Molino III which enjoyed great success in Western Europe mainly.

After signing with a new label (Barclay), he recorded his first solo album A Different Man in 1991 in California that he co-produced with his friend, drummer Pat Mastelotto.

Contrary to what he used to do in the Cock Robin albums, Kingsbery recorded a cover version of How Can I Be Sure, a hit by the band The Rascals dating from 1968.

Recorded in various studios (in Los Angeles, London, Paris, Toulouse, Biarritz and Brussels), he continued to use classical instruments (strings, trumpet and harmonica).

It was not until 2002 that the singer's new album could be found in stores, completely atypical both in style and in the language: with the exception of one song, the CD is entirely sung in French.

In June 2012, Peter Kingsbery was the featured vocalist on Danish duo Terminal Argh's debut-single "Middle of a Western", digitally released by Mabel The Label.
