London-based trumpeter and composer Loz Speyer may be best known for his own bands, Time Zone (Afro-Cuban Jazz fusion), Inner Space Music (compositions for improvisers, with Chris Biscoe), and Loz Speyer Quartet (Thelonious Monk's music as well as his own). He's also involved in a free improv trio (with Tony Marsh and Olly Blanchflower), a jazz standards Quartet (with pianist Paolo Losi), and in Proyecto Evocación (based in Santiago de Cuba - a collaboration with master percussionist Rafael Cisneros).

His musical experience includes working with Clifford Jarvis, Yann Tiersen, Steve Buckley, Amancio daSilva, Alex Maguire, Hugh Metcalf, John Bennett Band, Disassembler with Mark Lockheart, the Happy End, Test Department... in the innovative 12-piece Rare Mix with the likes of Jason Yarde, Brian Abrahams, Ben Davis, Julian Seigel... and in Cuba with veteran trumpeter Inaudis Paisán, Orquesta Chepín-Chovén, and Marcos Fernandez (pianist now with Eliades Ochoa).

His compositions for large ensembles, much acclaimed by those who know them, have been performed and recorded by jazz orchestras at the Guildhall School of Music and Morley College, and by Rare Mix... and his arrangement for Octet of the 'the Bastille Concerto', composed by Clifford Jarvis' father, made a fitting centrepiece in the memorial concert at the Spitz in honour of this great jazz drummer.

Speyer's teaching work, which he fulfills with a passion, ranges from small group trumpet lessons and whole class band workshops with school children, to leading workshop rehearsals of his own compositions with diploma students at the Guildhall School of Music.
