Lassus (c 1530-94) was a celebrity musician in his day, moving between his native Low Countries to Rome and Munich. At least 2,000 of his masses, canticles, motets and hymns have survived. He was also bipolar, then called "melancholia hypochondriaca". This may or may not explain the harmonic adventure which leaps out of his prodigiously inventive compositions, from the exotic sensuality of Veni in horum meum to the spiky moral indignation of Quid gloriaris in malitia. With lively support from His Majestys Sagbutts and Cornetts, the Choir of St John's College, Cambridge takes full advantage of this treasury of vocal colour with exuberant, full-toned precision and impressive musicality.
