Beautiful multi-textured analogue electronics rooted in ambient and club sounds, combined and juxtaposed with a freely improvised acoustic ensemble featuring four inspirational UK improvisers, Tullis Rennie (electronics), Tara Franks (cello), Cath Roberts (baritone sax) and Dee Byrne (alto sax).
Tullis Rennie describes the inspiration for this music as being “the beautifully human endeavour of trying to grab hold of unrepeatable moments: a second of magic within a spontaneous musical improvisation, or during a jungle tune breakdown on the dance floor of an intimate club space. When a light hits something and you freeze, wanting to make it last an age… but the reason moments like these are so alluring is precisely because they’re so fleeting.”
It really is wonderful, and you can truly hear this intention in the music.
"Blending string improvisations and outré brass with expertly deployed electronics and samples...equal parts tender and affronting, slaloming gracefully around conventional approaches to rhythm, melody and harmony with a lexicon that’s unmistakably his own” Electronic Sound
