This Naxos disc collects multiple Concertos, but with a continuo instead of an orchestra. Although not to be played at a single sitting, these works offer a great deal of pleasure, stemming from their rich textural interplay with plenty of imitation among the soloist. The quality of invention is astonishingly high. Il gardellino (which opens the programme) is justly famous, but the G minor work, RV 107, is also remarkable, with a touching Siciliano slow movement; it ends with a chaconne which maintains the minor key. RV 88 has a strikingly cheerful opening movement, then gives prominence to the flute both in its central Largo cantabile and in another chirping finale. RV 89 effectively brings a change of colour in the use of a pair of violins in juxtaposition to the flute. The performances here are admirable and the recording is most effectively balanced.
