It was clever of Philips to couple Sibelius's least popular symphonies with the extremely popular Violin Concerto and tone poems. Don't let the words "least popular" scare you off, however. If you like Sibelius, you'll love the Third and Sixth Symphonies. The latter, in particular, is one of the most purely beautiful pieces of music in the history of sound; its only flaw is a quiet ending that makes conductors unwilling to play it at live concerts. Sir Colin Davis and the Boston Symphony perform all of this music with idiomatic flair and unflagging enthusiasm. These versions are far superior to Davis's recent remakes on RCA, and a lot cheaper too. So go ahead, indulge. --David Hurwitz
