R4 has been around for a long time and I have really enjoyed his ability to merge ambience with noise. R4 is the work of one Barry Sheffel, who is also the man behind the Fusion Audio Recordings label. He had dropped off the face of the earth for a while, but he is back with a lot of new work, of which this is one. The label describes this simply as “Noise and quirky, leftfield electronics. Recorded in 2021. This is the second in series of mini CDRs.”

This disc consists of two tracks. We kick it off with “Traffik,” which is a short track of noise with a psychedelic feel. Lots of analogue noises and static, with a whimsical quality. It’s almost like he took honking cars and inserted them into road noise and theremin-like noises. “Two Point Seven Degrees Celcius” closes it out with a 17 minute track that really leans into the electronic noise with analog warbling, stuttering electronics, and shortwave radio transmission noises. There is a lot going on here that keeps it moving, and the music is layered in such a way as to continually build in both complexity and intensity. It ends quietly and deliberately, pulling you in, as it unravels in complexity to a static noise drone and then to quiet bass rumble. Nicely done.

This disc, along with his other recent output, such as “Rainmaker” on Inner Demons Records, show that R4 is in fine form and continues to produce noise music that is engaging and inventive. The 3 inch format really highlights R4’s work, with just enough length to construct a good track but not so long that it gets tiresome. Really solid noise. This album weighs in at just over 21 minutes and is limited to 15 copies, so get it while you can.
