This ECM box set brings together three early Jan Garbarek albums, made between 1971 and 1975, and all featuring fluently inventive Swedish jazz pianist Bobo Stenson. The players were the emerging young stars of the Scandinavian scene, and though the music is uneven, its growing independence is palpable. Sart reflects both Miles Davis's late-60s fusion and Coltrane's and Albert Ayler's free-sax odysseys (in Garbarek's high, squealing dissonances and battering runs), while Witchi-Tai-To is steered by Stenson's affection for folk-song melody. But 1975's Dansere finds Garbarek beginning to leave orthodox jazz-sax methods behind, his tone now unique, his phrasing sparing. The spine-tinglingly lonely hoots on trances like Skrik & Hyl and Lokk represent the Garbarek his regular admirers know. There's also a perceptive background essay - in a rare piece of exposition for ECM - by Michael Tucker.
