Haii, added you on Discord. We currently have an experienced dev (you can check my past jam entries: https://kawakamiidv.itch.io/), 2D artist and a composer, though we still need a more experienced composer/sound designer. Plus 2/3 members speak RU >_<
our game idea: action FPS mixing 2D & 3D art, set on a train with zombies. (can tell more in DMs)
in terms of music & sounds we'll need a dynamic action track + all sorts of weapon sfx, train, ambience, zombie & UI sounds, so there's plenty of room to be creative!
