Fresh from a sell-out performance at a Celtic festival in Glasgow, Motu :: Oileáin, which translates to "islands" in te reo and Irish, explores the musical connections between the two cultures - which are more numerous than you might think.
The project began last November when four of Ireland's most celebrated musicians collaborated with platinum-selling trio Trinity Roots, resulting in music described as a "contemporary conversation" that nevertheless looks to the strong traditions of both cultures.
The performers' respective histories of love, war, oppression, politics and protest reveal a deep bond that generates tribal chants married with fragile harmony and evocative melodies with hypnotic grooves.
"The soul connection we share with the Trinity guys has its roots in music, but it turns out we share much more," says Irish singer Pauline Scanlon. "Humour, history, indigenous language and culture but, above all, rebel hearts."
