The opening piece on the disc, a 12-minute Adagio, features a few attractive but not really memorable ideas. It ends somewhat ambiguously (nothing new when it comes to Sibelius), here suggestive of more to follow--but what that might have been we will probably never know. A tiny fragment of the original ending of Voces Intimae only a few seconds long fulfills BIS's intention to record every scrap of music that Sibelius wrote; but the disc concludes sonorously with the Andante festivo, taken at a good clip and sounding less solemn than usual in this reduced format. As suggested with respect to the major works, the Tempera Quartet handles all of this music expertly, and BIS's sonics are the most consistently excellent in the business. Do try the B-flat quartet: its quality will surprise you.
