It's not often you hear a jazz album where the French horn is the lead instrument. ‘Charming’ is the adjective that most readily comes to mind in describing the results – which means that punk-jazz devotees probably aren't going to be going out and buying Triplicity in droves. But that's not the audience Jim Rattigan – the UK's premier jazz French horn player – was aiming at in assembling this trio, which combines sounds and instruments in a manner that you might think would be better attuned to the classical repertoire. Of course, Rattigan himself has major classical chops – he played with the Royal Philharmonic for six years, and the pastoral ‘Barton Glebe’ here takes its cue from a Brahms trio – besides an impressive CV in more or less every other area of contemporary music making. His collaborators are terrifically adaptable too, not to mention talented, as they demonstrate on this set of varied Rattigan originals. If ‘Sweet Tamarind’ waltzes into tea-dance territory, ‘Blitzar’ provides some bite and ‘Off the Rails’ contains a welcome hint of dissonance and chaos, and some sparkling improvisation.
