Exactly 30 years and 3 months ago Leo Records was promoting a three-day international music festival called Unsung Music. The event was held at the Royal Festival Hall, London. The idea of the festival was to present innovative, improvisation-based music that had never been heard live in Great Britain before.

Spool 30 years forward, and this kind of music is regularly heard in many venues. To celebrate the thirty-year.25 anniversary of this music, Leo Records will present a one day celebration bringing the best practitioners of this genre to Cafe OTO. As part of the celebrations, we'll also be hosting a special matinee screening of the documentary, 'Leo Records : Strictly For Our Friends'.  

Evan Parker

"If you've ever been tempted by free improvisation, Parker is your gateway drug." - Stewart Lee 

Evan Parker has been a consistently innovative presence in British free music since the 1960s. Parker played with John Stevens in the Spontaneous Music Ensemble, experimenting with new kinds of group improvisation and held a long-standing partnership with guitarist Derek Bailey. The two formed the Music Improvisation Company and later Incus Records. He also has tight associations with European free improvisations - playing on Peter Brötzmann's legendary 'Machine Gun' session (1968), with Alexander Von Schlippenbach and Paul Lovens (A trio that continues to this day), Globe Unity Orchestra, Chris McGregor's Brotherhood of Breath, and Barry Guy's London Jazz Composers Orchestra (LJCO). 

Though he has worked extensively in both large and small ensembles, Parker is perhaps best known for his solo soprano saxophone music, a singular body of work that in recent years has centred around his continuing exploration of techniques such as circular breathing, split tonguing, overblowing, multiphonics and cross-pattern fingering. These are technical devices, yet Parker's use of them is, he says, less analytical than intuitive; he has likened performing his solo work to entering a kind of trance-state. The resulting music is certainly hypnotic, an uninterrupted flow of snaky, densely-textured sound that Parker has described as "the illusion of polyphony". Many listeners have indeed found it hard to credit that one man can create such intricate, complex music in real time.

"Mark is just incredible and immensely diverse, he is at the center of "Kwingyaw" and it is difficult to tell what he is doing to get some of these sounds." – Bruce L Gallenter, Downtown Music Gallery, NY
