Founded almost by accident by baritone saxophonist George Haslam, SLAM has now been going a quarter of a century – and, since Dvorak and Dunmall were among the first artists to release on the label, this makes for an appropriate anniversary release. They are joined by fellow SLAM veteran Sanders, and Mapp in his label debut. Together they present seven magnificent, Mingusesque tracks – Dvorak's distinct compositional voice blended with intense, impassioned improvisation. Mapp and Sanders make for a powerful, highly dynamic rhythm section, and there's tremendous interplay between trumpet and sax, twirling around one another in a horn double helix, for instance, on the Chaucer-channelling ‘Millers Tail’. Occasionally Dvorak even breaks into song and spoken word, inspired by Zappa on ‘Zapped’ and Lord Buckley on ‘Gettys Mother Burg’. These two moments may not be for everyone but he just about pulls it off – and the disc as a whole is superb.
