full_context: Document 1: Africa/Brass: Africa/Brass is the eighth studio album by jazz musician John Coltrane, released in 1961 on Impulse! Records, catalogue A-6. The sixth release for the fledgling label and Coltrane's first for Impulse!, it features Coltrane's working quartet augmented by a larger ensemble to bring the total number of participating musicians to 21. Its big band sound, with the unusual instrumentation of French horns and euphonium, presented music very different from anything that had been associated with Coltrane to date.
Document 2: Zero Set: The music on "Zero Set" is strongly influenced by African rhythms and music. One track, "Recall", features Sudanese vocals by Deuka. Matthew Weiner describes it for Soulmind Online: "Though not a dance record per se, "Zero Set" is one of the earliest extensions of Krautrock’s possibilities on the dance floor, pitting the profoundly electronic sequence patterns of Plank and Moebius against the hyperactive percussives of Guru Guru drummer Mani Neumeier. On tracks such as the prophetically titled 'Speed Display' and 'Pitch Control', the phasing, chattering and decidedly Germanic grooves found on Zero Set constitute vibrant proto-techno at its earliest and finest." David Ross Smith, writing for Allmusic, describes the album: "...a highly percussive affair with Mani Neumeier. The album is saturated in drum and synth rhythms and polyrhythms, resulting in compositions that are energetic and infectious." Zero Set was a turning point for Moebius and Plank, a fact lamented by Steven and Alan Freeman in their book "The Crack In The Cosmic Egg". They say, in part: "...working with Mani Neumeier on Zero Set strangely took the music too close to techno for comfort..."
Document 3: London: London has numerous venues for rock and pop concerts, including the world's busiest arena the o2 arena and other large arenas such as Earls Court, Wembley Arena, as well as many mid-sized venues, such as Brixton Academy, the Hammersmith Apollo and the Shepherd's Bush Empire.

The Allmusic review by Richard S. Ginell awarded the album 3 stars and states ""The African Game" is a major statement, a highly eclectic, nine-part, 45-minute suite for augmented big band that attempts to depict no less than the evolution of the species from the beginning of time to the present from an African perspective. Well, yes, this theme has been taken on by many an ambitious artist in every field, but Russell's work is remarkably successful because it tries to embrace a massive world of sound in open, colorful, young-thinking terms, with degrees of timbral unity and emotion to keep the idioms from flying out of control".
