"The main attraction on this disc is the Berio orchestral arrangement of the Clarinet Sonata op.120/1. Like Schoenberg, it’s a harmonically and melodically “straight” transcription, not a modern re-imagining of the work. Berio, no stranger to orchestrations and adaptations - Puccini’s Turandot, works by Schubert, Mahler, and Verdi - tackled this last major work of Brahms’ for reasons we don’t know. Iosif Raiskin speculates that the tinges of Mahler in late Brahms may have been a reason for the Mahler-loving Berio. Be that as it may, the result is a wonderfully graceful Brahms Clarinet Concerto.

Admirers of Luciano Berio's Sequenzas have long wished for an affordable, high-quality collection of these masterpieces for solo instruments, considered by some to be the core works in the composer's oeuvre. Deutsche Grammophon released Ensemble InterContemporain's fabulous set in 1994, but its relatively high price and incompleteness make it a second choice when compared with the 2006 set on Naxos, which is both reasonably priced and complete, now that Sequenza XIV for cello appears on CD for the first time. Of course, bargaining over cost and completeness is one thing, but artistic quality is another important consideration: how does the Naxos edition fare in its performances and sound quality? While Ensemble InterContemporain's terrific compilation practically guarantees accuracy and authenticity – many of Berio's original musicians were involved in the project – the performances on this triple-disc set are quite comparable and wholly convincing in virtuosic skills, lustrous timbres, and splendid recording quality; only an adept student of these pieces could note any discrepancies, and those would be minor.

The Alban Berg Quartet excel in 18th-century repertory and the Franz Josef Haydn found here makes up an especially excellent example of this ensemble’s playing. The music is great, too: the two late Op. 77 Quartets quartets are what I believe are the finest examples he penned in this genre.
