Average quality
First of all the scene direction is very bad and awful.
The quality of the singer is quite average.
David Walker's voice is not high enough to reach Goffredo's texture. Christophe Dumaux in René Jacobs' edition (CD) is much much better.
The other singers are ok but from a baroque production I would expect more.
I think that the best "player" is the orchestra, which is very good.
