Recorded in concert at the University of Sheffield in March 2025, Reality Is Not A Theory is the first collaboration between Mark Fell and Pat Thomas. Major figures in British experimental music since the 1990s, Fell and Thomas have developed their rigorous practices from radically different backgrounds and perspectives: where Fell’s singular take on synthetic abstraction emerged from Sheffield’s electronic underground, Thomas is a virtuoso improvising pianist steeped in jazz and modernist art music who has simultaneously worked with sampler-based electronics for decades. As the record’s wonderfully academic subtitle explains, we are presented here with two sides of ‘algorithmic and improvised music for computer and piano’, exemplifying both players’ insatiable search for new (and sometimes uncomfortable) playing situations.
The performance begins with Fell’s electronics close to the timbres of acoustic percussion, attacks that suggest wood, metal or glass threaded along a rapid pulse while Thomas focuses on the lowest registers of the piano, deadening the strings. As Fell’s electronics start to ring out and occupy more harmonic space, Thomas turns to wide, repeated clusters, which slowly expand into patterns of chords. Like in his recent solo recordings and his trio work with Joel Grip and Anton Gerbal, Thomas’ playing combines extreme dissonance with a deep lyrical sense. Fell’s work gradually shifts its focus toward drum sounds, drawing on the microtemporal processes that have characterized his practice in recent decades. Heard together with Thomas’ probing piano, the computer sounds call up unexpected associations with the klangfarben antics of improv drummers like Paul Lovens or Tony Oxley. Throughout its second half, the music grows increasingly frenetic, as Thomas sounds out rapid, irregularly repeated figures and beautifully sour chords in the upper register, while Fell’s percussion develops into angular pan-pipe-like feedback and waves of glissandi.
With great confidence and patience, Fell and Thomas often let their individual contributions remain rhythmically distinct and unsynchronised, allowing unexpected correspondence and coincidence to guide the music’s development. Recorded in a hall named after Sheffield steel manufacturer and Master Cutler Mark Firth, the location might suggest a model for understanding how Fell and Thomas interact here: two workers in the same workshop, each immersed in their own part of the production process. Arriving in a striking sleeve designed by Mark Fell, with liner notes by Francis Plagne, Reality Is Not A Theory is an invigorating document of the meeting of two mavericks of contemporary music.
