That was pretty weird and experimental, but that makes sense for jazz ^^
If you guys are first-timers, this is a pretty good start! It sounds chaotic but it does kind of hold together with the drums. It sounds like you're also playing with samples with the scream and the voice? It seems like there was effort put into this.
Keep playing around with the app and play around with different melodies. I don't use Bandlab but I have a friend who uses it who was able to make some really complex lo-fi hip hop tracks, so I know it's a versatile app. Keep playing around with it and you guys can only get better and better ^^
