As well as the guitar and the piano, O'Connor also played the flute, both metal and wood based flutes, as well as an Electric Wind Instrument (EWI) which allowed for a wide variety of instrument sounds to be produced on one instrument. He also played percussion, the bass guitar and keyboards. O'Connor usually worked as a solo artist, playing all instruments in his recordings. He did, however, collaborate with guitarist, Paul Clement, on the album, "Summer Rain", with songs co-written by both artists featured on the CD. Clement was also played the guitar on "Mariner", "Tales of the Wind", "Bushland Dreaming", "Lovesong", "Live in Concert", "Dreams and Discoveries" and "Whispering Sea".
