What I can say is that the results sound convincing, especially as the performances are sharply delineated and sympathetic and the additions are not overdone. Nothing in these performances is in bad taste or contrary to the spirit of the music. Try listening to No.8, the ‘Christmas’ concerto, especially the familiar pastoral finale.
Perhaps these enhanced versions are not for hearing every time, but they certainly serve well as an adjunct to the Avison Ensemble or if you have an earlier collection such as those directed by Trevor Pinnock, Roy Goodman, Nicholas McGegan or Chiara Banchini (from MusicWeb review).
