This is a lovely vintage recording, arguably superior to Bohm's later account on EMI. The singing is beautiful, and the orchestra superb. Bohm's reading is measured but well-paced.
Contrary to the misinformation given in the first review on this page, this Decca recording was made in 1955 (NOT 1951).
The recording is one of the very first to be made in stereo. The sound is not up to modern standards, but is far ahead of other recordings made at the time. The orchestral strings sound rather thin at times, and the singers appear to be very closely mic-ed, but the wonderful performances far outweigh any shortcomings of the recording.
There are a number of small cuts to the score (hence the fact that the opera fits onto only 2 CDs), but otherwise it is performed complete. Its bargain nature makes this recording well worth having as an additional version even if you already own a copy of Cosi. Overall this is one of the best recordings available of this opera.
