Trombone quartet Slide Action won the 68th ROSL Annual Music Competition Mixed Ensembles Section Prize on Tuesday 6 October and were awarded £10,000. Among four ensembles, the ensemble impressed the jury with their exceptional blend and musicianship. 

Following a seven month delay, this year saw wind quintet Pacific Winds, saxophone, violin and piano ensemble The Kavinsky Trio; Tango group The Nuevo Tango Ensemble, and Trombone Quartet Slide Action who battled it out for the £10,000 prize and made for an eclectic and exciting evening of musicmaking. The adjudicators Gavin Henderson CBE, Geoff Parkin, Sarah Field and Huw Wiggin had the difficult decision of choosing the section winners, who also won the Philip Jones Prize for an Outstanding Brass Ensemble.

The ROSL Annual Music Competition grew out of a series of concerts inaugurated at Over-Seas House in 1947 under the banner ‘Festival of Commonwealth Youth’. The Festival became competitive in 1952, with a first prize of £10.
