rockin' it: definitely a nirvana influence there
this is pure grunge, a great callback to the 90s garage grunge sound, which has just as much to do with the equipment used as with the loud recording style and sound... cool stuff. i like the clean guitar part during the verses (there's a little high note in there on the 'lead' guitar that really does it for me), it switches up the perception of grunge needing constant barre chords to really rock. the vocals during the heavy pre-chorus are especially reminiscent of cobain, but you can actually use use vibrato in your voice, which is something cobain never could pull off, so kudos for that!
the sound quality needs work, but duh. there are a couple of times where the drums seem to kind of trip through the fills and rolls, but other than that, the performance and arrangement is solid. since you said this is your simplest song, i'd love to hear some of your more complex songs.
rock on!
