A medium price Naxos disc (8.572866) includes Violin Sonatas Nos. 1-5 and No.8 from Book 2. Adrian Butterfield (violin), Jonathon Manson (viola da gamba) and Laurence Cummings (harpsichord) are the performers.
Les Arts Florissants conducted by William Christie are the superb artists on a budget price Harmonia Mundi CD (HMA 1951238), which contains 4 Cantatas, including “Arion”.
Nos. BWV 49, 115 and 180 are included on a very fine Naïve medium price disc (NC 40031). The soloists include Barbara Schlick (soprano), with the Concerto Vocale Leipzig and Ensemble Baroque de Limoges conducted by Christopher Coin.
The Collegium Pro Musica, an Italian group, are the accomplished performers in all 6 Op.13 Sonatas on a super budget Brilliant Classics CD (95077). The recording quality is excellent.
Probably the best way to buy these German Arias is via the Erato 5 CD box (0825646112265), which is available for less than the price of 1 full price CD. Emma Kirkby (soprano) is the featured artist in the set, and the other 4 discs include Dowland, De Wert Madrigals, “A Vauxhall Gardens Entertainment” and songs by Robert Jones. This set really is a superb bargain.
