Regarding mic’s a few months ago I also purchased a pair of Uši Pro. They made using my Zoom H4N, whose built-in mics are total garbage a joy to use again. They are cheap and highly desirable so can be hard to get a hold of but it’s worth the effort.

For some inspiration check out NFSA’s “Lateral Listening” series. Sorry, I can’t find an easy way to share all there shows so just do a google search. Features artists such as Robert Curgenven and Lawrence English.
