The assembled crowd at Cafe OTO chant their collective approval as Konstrukt's 72-minute improvisation, argued alongside a trio of simpatico British guests, reaches a conclusion and the audience's palpable enthusiasm is understandable. This is music that drowns the senses in the sheer joy of sound-making: its grand structural sweep and ferocious energies demand attention and Cafe OTO attendees were fully prepared to submit. Konstrukt hail from Istanbul and previous projects have involved a range of starry guests, including William Parker, Thurston Moore and Marshall Allen; Alexander Hawkins played on their live 2015 album, also recorded at Cafe OTO, and Daniel Spicer and Alan Wilkinson are likewise well placed to contribute to this latest set, which is rooted in American fire music while also exhibiting strong hints of Eastern mantras. A killer combination that conjures up welcome memories of late 1960s Pharoah Sanders and Marion Brown Impulse! records. Whether this music's grandeur and sense of place and time can be well served by the cold distance of CD, though, is open to question. At around the 28-minute mark the unfolding whole is broken by a quiver of applause, but moments that play well in the venue don't necessarily translate to the isolation of your own room or headphones. What's the story with that sudden funk bassline – Michael Henderson meets Prime Time – that emerges shortly after the applause to quickly disappear again? What exactly stirs up those sudden pile-on nests of free-jazz ensemble pomp? Windows of spectacular clarity do pop up – Alexander Hawkins asserting a mechanistic riff and, later on, flooding the space with cascades of clusters and the distinctive sound of Korhan Futaci's gralla (an ancient double-reed instrument, an antiquated oboe) – to act as markers. But otherwise you need to sit tight, suspend your disbelief, and prepare to be swept alongside in a slipstream of sound.
