Music interview: Pianist Paul Harrison on the controlled experiments of jazz quartet Sugarwork

There’s nothing saccharine about Sugarwork. The quartet, formed by Glasgow-based pianist Paul Harrison, combines decidedly non-traditional avenues of improvisation and pre-composed music with a simmering reservoir of electronica, from industrial to psychedelic. Having just released their eponymously titled debut album, with an Edinburgh launch at the city’s Jazz Bar on Thursday past and a Glasgow gig at the Blue Arrow in Sauchiehall Street tonight, the band assembles four of the Scottish jazz scene’s most inventive and open-minded musicians – Harrison playing piano, keyboards and effects mixing, Stuart Brown on drums and percussion, tenor saxophonist Phil Bancroft and guitarist Graeme Stephen.
