Adam Bohman is also a familiar figure on the London improv circuit, typically to be seen hunched over a table filled with a bewildering array of gadgets and everyday objects (as illustrated in the booklet photo here) from which he methodically extracts sounds, a shock of red hair either side of his pate, looking equal parts obsessive professor and bemused fourth-year geography teacher. He pops up from time to time in the London Improvisers Orchestra, and he and his brother Jonathan have, in the past few years, instigated and run small gig spaces - the now defunct Charteris in north London, and the Bonnington, in south-west London - at which they regularly perform in what is, it has to be said, a rather painful duo, which is in turn frequently augmented with a guest musician.
