The title's dedicatee, David Mossman, was the founder of the Vortex live music venue in east London, which, as Evan Parker points out in his liner note, “[for] over 30 odd years has become an essential part of London's musical life”. But, while we're honouring longstanding musical institutions, this trio itself is surely a contender. Their new offering – recorded at the Vortex, naturally – is the latest in a series that began in 1980 with the now out-of-print Tracks. Their shared history goes back a lot further than that. Parker's friendship with drummer Paul Lytton began more than half a century ago in 1967, while Parker and bassist Barry Guy were working together as part of Spontaneous Music Ensemble as early as 1966. Unsurprising, then, that the three of them trade in a dense, information-rich music through which they seem to achieve the holy grail of free-improvisation: the group mind. In a sense, it feels like those early experiences with SME, trying hard to navigate a path away from American free-jazz, have come full circle, as the three of them dig with a bullish, muscular energy and Parker's tenor sounding gruffer than ever. Make way for the originals.
