SEED Ensemble released their first full album, Driftglass, in 2019 on the Jazz re:freshed label.

Driftglass was positively reviewed by The Guardian, who described the style as a fusion of "African, Caribbean, dance grooves and 60s Blue Note".^[10] Clash Magazine called the album "a bold record", and Kinoshi "a stellar instrumentalist".^[11]
