Great collab
Really love how this comes together. Kind of reminds me of older bands as well with weird music videos to go with their music too. Your vocals sound great though. The tune feels pretty good although there are mine mess ups. You make me think of the singer from Tool too so that's nice.
The guitar sounds smooth here except when transitioning to the chorus. Mostly since it sounds like you may have accidentally hit an additional note when transitioning on this one. The bass sounds smooth here and has a nice solid rhythm with it.
The drums here sound really nice and he sounds like a great drummer too. The guitar solo was nice, kind of slow but very smooth on the ears.
Overall ,great rock song collab.
