The eloquent and dedicated Manchester saxophonist Nat Birchall's music has long focused on the textures and nuances of John Coltrane's saxophone sound rather than its famously torrential virtuosity. He's joined here by familiar partners on the latest leg of that journey, including Adam Fairhall whose exploration of the resonating hum of the harmonium throughout this session signals Birchall's intention to visit the crossing-points of jazz and India's raga traditions. Andy Hay's rustling shakers and Michael Bardon's slow-bowed bass open the tranquil ‘Man From Varanasi’ (a tribute to Indian shehnai master Bismillah Khan), and Birchall's tenor solo builds from shapely lyricism to dramatic multiphonics over Hay's brushes groove. ‘Humility’ is a poignantly prayer-like tenor elegy with a percussion-centred core, much of ‘A Prayer For’ is a gentle ascent of crisscrossing harmonium lines underpinned by a quiet bass vamp into which Birchall sonorously drifts, and ‘Dervish’ is an exultant high tenor motif that climactically spurs the saxophonist to his most impassioned flights. Cosmic Language is another haunting corner of the big picture that the unique Nat Birchall is devoting his life to painting.
