I have this on my backlog of Jams to go through, but peeked ahead hoping to see Alekswithak in there, and indeed, it's him. He's already scored a few great SP mods : Alkaline, Dwell, Dwell 2 - which should also be checked out - and some of his tracks have been featured in various map jams as well. He hasn't published the soundtrack for QBJ3 yet, but I assume he will eventually. Until then, enjoy the rest at https://alekswithak.bandcamp.com/
