John Eliot Gardiner's interpretation of the Missa Solemnis stands as one of the crowning accomplishments of his career and one of the most impressive achievements of the period-instrument movement. The concept is grand and powerful, lively though not unduly brisk. The execution is simply electrifying: Gardiner has the orchestra on the edge of their seats, the chorus going all-out, and sparks flying everywhere. Excellent singing from the soloists and a vivid recording complete the triumph, and it's all on a single disc. --Ted Libbey
