The theme of instrument design recurs with New Music for a New Oboe, Volume 1, which sees the excellent Christopher Redgate putting a redesigned version of the instrument through its paces. It’s always a joy to hear Redgate play anything at all, but this coupling of works by Edwin Roxburgh and Michael Finnissy does fine justice to the Howarth-Redgate instrument (T. W. Howarth being the woodwind specialists who manufactured it), with its increased range and improved facility for microtonality and multiphonics.
