This mix is hot like 'The Ghost of FM', Groucho's vocal is hotter in the mids than any other recording I have heard of his vocal, and this is good ... Did we get a new mic ?
At 0:59, some crafting there, can deliver a cleaner entry on your vocal, draw the envelope a little earlier on the instruments ... tighten that hairpin sooner as we approach the vocal entry ... and pop that fader up on the vocal just before that entry, then ride it down if you think you need to ... envelope - fader ... whatevuh ...
Hey, she can come over here and do yoga ...
'eat over the sink' ... excellent, and you are only allowed to take one bite, two chews, and you have to swallow as quick as possible ...
I think the Harmonica is too edgy, I want to hear more music coming out of it, perhaps the real 'insane sound' should just be the guitar and you can further develop that, and your harmonica playing which is awesome, should be normal.
Perhaps the harmonica is mixed here to represent what you really, really want, from the guitar ...
... that would give us more contrast between the 'burning platic adhesion to our skin guitar' ... and the 'real authentic blue harp' ... IMHO. Back off on the harp, and maybe you can approach the guitar more irrationally
If you are trying to make us guess at 3:04 which is guitar and which is harp, you are getting close ... no telling what that shrieking monster is ...
At 3:40, the instruments in general are creeping up to levels that are competing with your voice.
At 4:00, this 'puffing on the harp', slap some meaningful delay on that sucker ? IMHO
Wild man, unique, original, awesome ... when you guys gonna get tired of being the stars around here huh ? ;-)
