I've been badly, badly wanting to record a few sides of my own (which I could do easily enough myself ... just Django-style guitar and vocals), getting them pressed on a shellac equivalent, then playing them and selling them (at cost) at my windup DJ gigs.
Currently at said DJ gigs, I'll occasionally plop on a not-too-cluttered instrumental (like Jimmy Noone's "Sweet Lorraine") and grab a couple vocal choruses with my megaphone/mic combo.
But this would be next-level ish!
So, I'm indeed very excited to read your post here and I could be a customer in perpetuity!
