Gramps! Conceptually, this is awesome. Its dirty and dark. How-so-neva(as the old folks used to say), the production is sorely lacking. You gotta make this with a band brotha!!! And just maybe you could come up with some kind of chord progression, but nothing that takes away from the darkness and the dirtiness. Gotta keep that. The one chord thing isn't doin' it for me. It might have if there was some heavy ass bass. Anyway...the synth needs to go. Replace with a guitar with some kind of effect. Please make this again in a real studio with a full band. It invokes a lil Howlin' Wolf vibe.
