Their record label describes them rather laboriously as “a Baroque super-group of four superstar Baroque instrumentalists”, but the Retrospect Trio don’t need any fancy titles to prove their quality. Bringing together violinists Sophie Gent and Matthew Truscott (leader of the OAE) and Jonathan Manson on bass viol (principal cello of the Amsterdam Baroque Orchestra) under the direction of young harpsichordist Matthew Halls, this ensemble is all about unshowy musicianship. Joined last night by soprano Julia Doyle they offered up some of the best Purcell London is likely to see this year – with performances from Mark Padmore and the Britten Sinfonia, not to mention Scholl, Jaroussky and Ensemble Artaserse still fresh in the ears, that’s saying something.
