Rockoon is the fourth studio album by Japanese Jazz fusion band T-Square (then known as The Square). It was released on April 1, 1980.
Takeshi Itoh (saxophone player) had begun to use the Lyricon (a Woodwind Synthesizer) in their albums from 1980 until 1987. He switched to Yamaha WX11 and finally to AKAI EWIs in 1988 and has since been using EWIs as a secondary wind instrument.
