What is the best recording for St. Matthew's Passion sung in English?
I have the Willcocks--Robert Tear and Shirley-Quirk are top class singers, and there's nothing _wrong_ with this performance, but performance practices have come a long way in 30 years (largely, in my opinion, for the better). I assume you have your reasons for seeking a performance in English, but it's very rarely I would listen to this rather than Suzuki or Gardiner doing the original text. Bach is worth brushing up one's German for.
I also have the Willcocks version. The performance is nice, but the audio quality isn't great. The audio is uninspiring enough that I wish I'd have gotten a better recording in German instead.
Samples from this Dunedin Consort recording sound really good: http://www.linnrecords.com/recording-matthew-passion.aspx
