A lot of Ujico's albums as Snail House are more chill/downtempo, but I love the Alien Pop series. Really creative producer. Here's his Bandcamp for those new to him: https://0101.bandcamp.com
I don't think he's a permanent member of any circle but he also does some clubbier tracks on doujin releases: I've heard him on compilations from Wavforme, Unitone, and Riparia Records.
