David Toop is a pioneer in British experimental and improvised music: a sonic voyager who has continuously challenged the sources and materiality of sound through rigorously thoughtful performances, a vast catalogue of recordings, and a steady flow of highly influential texts. His first outing with Italy's radical composer, percussionist, vibraphonist, and multidisciplinary artist Sergio Armaroli has a sprawling sense of beauty and intimacy.

Featuring Armaroli on vibraphone and prepared vibraphone and Toop on electronics, "And I Entered Into Sleep" is a sonic journey into the unconscious between electronic and acoustic sounds. The pair weave a striking interior world of immersive psychological depth.

Feeling almost subaquatic at times, like captured glimpses of rumbling, shadowy ecosystems lost within murky ambiences, before washing ashore in a series of pointillistic, highly detailed alien landscapes of the mind, each artist's markedly different sound-sources, and treatment of the subsequent material elements, dance in abstract grace, incorporating subtle nods to minimalism, free jazz, and musique concrète within its seamless total form of sparse texture and tone.
