Rasmus Rasmussen (Aerosol, Causa Sui) and Keith Canisius are back with another delightful set of Astral TV tracks. Since their debut album, "Chrystal Shores" from 2017, the Copenhagen-based duo have refined and perfected their approach to making semi-improvised synthesizer music. Musically it doesn't get much more pure than this. From their vast assemblage of synthesizers - that is, vintage, modern, digital, analog and modular synthesizers - the two producers are squeezing the finest sonic essence, for your neural pleasure. Forget about song structures and leads - it's not that kind of album. Listening to "Travelling The Circuits" is like floating on an electronic river through a slowly changing scenery. There's really no story here, and it's not about the destination. It's about colours - lots of colours. And the tactile beauty of sounds and patterns, filters slowly opening and closing, letting your senses tickle by a unique 80hz oscillation that only a wood-panelled analog synth from the early 1980s can produce. "Travelling The Circuits" is a true auditory delight.
