Jazz gigs of the week (08/12/12): Roller Trio, various venues Nominated for Mercury, MOBO and JazzFM awards, the trio who met at the Leeds School of Music - saxophonist James Mainwaring, garage-y guitarist Luke Wynter and drummer Luke Reddin-Williams - combine spikey riffs, electronics, and a cosmic sense of time and space. They're part of the F-Ire Collective, which aims to "sustain the creative lives of their members and the surrounding community; to ensure that their creativity functions well inside the wider community." Roller Trio's debut features the spiralling ziggurat rhythms of "Deep Heat" collapsing into the atonal "Howdie Saud-I," and smoothing out in "R-O-R": fluent, sax-led music rippling translucent broken guitar chords. Open your ears to a new world of jazz, music to see in the dark to.
