At 26, the cello virtuoso and skyrocketing Finnish maestro Klaus Mäkelä holds the titles of chief conductor of the Oslo Philharmonic Orchestra, music director of the Orchestre de Paris, and artistic director of the Turku Music, not to speak of his heavy schedule as a guest. On tour with his Norwegian cohort, Mäkelä traverses the complete symphonies of his compatriot Jean Sibelius. For an idea of what to expect, sample the same forces in the same repertoire on their new multidisc set for Decca. The nervous subterranean rhythms, the shimmering overlays of instrumental texture on texture, the plangent melodies that sing of a world still in touch with its origins—Mäkelä has the composer’s untamed Nordic landscapes in his blood. Mariss Jansons, who led the Oslo Philharmonic from 1979 to 2000, advanced a solid provincial band to the top ranks of international symphonic ensembles. Mäkelä seems poised to bring back their glory days. —M.G.
