To complement their opening-night première of bespoke new cross-genre compositions, the 80-piece Grit Orchestra, a hand-picked array of Scottish folk, jazz and classical artists, revisit the music that first made them, that of the late and much-lamented Martyn Bennett. Founding conductor Greg Lawson’s extraordinary live realisation of Bennett’s eponymous final masterpiece was their inaugural towering achievement, at Celtic Connections 2015, followed three years later by his orchestration of 1998’s Bothy Culture, which filled the Hydro to the brim with euphoria. Amid the über-conducive ambience of Scotland’s best-loved rock’n’roll ballroom, we mark 15 years since Bennett’s passing, while celebrating his continued legacy, with the first back-to-back performance of both works.
