Not sure if this is of interest to any of you, but I'm the guy in the video under discussion and wanted to answer a few of the questions that were posed.
First off, thanks for engaging. Any feedback is better than none. It is a live performance. Admittedly, the guitar doesn't sound so great, but then again I'm recording myself live on my patio with a pair of SM57s. There's plate reverb on both guitar and vocal, and the vocal has been compressed some with the opto circuit in Logic's compressor. That is the only processing.
As for the cigarette, it's an old mic technique I picked up down here in New Orleans. Okay, not really, but just wanted to flavor the song in a performative sort of way. That's not my usual thing.
