French Baroque violinist Amandine Beyer and her group Gli Incogniti have gained a reputation for lively performances of Baroque chamber music but this one is going to be tough to beat. It pairs the two François Couperin works titled "Apotheosis," one devoted to Couperin's French predecessor Lully, the other to Arcangelo Corelli. They're a fascinating pair, both aimed at the reconciliation of Italian and French styles, but in different ways, with Italianate instrumental work grafted with exquisite grace onto French court rhythms in the former, and French ornament added to a loose sonata structure in the latter. Beyer's violin seems almost to bloom from its surroundings, and the playing of all the musicians has a most attractive combination of crispness and warmth. Another attraction is the presence of a pair of early Couperin works designated "sonades," framing the two Apothesoses; these are rarely heard and put Couperin's later attempts to "reunify the tastes" into an interesting perspective. Add in superior sound from Harmonia Mundi, and this is, in sum, a release that may well be definitive for these works.
