I've been into Umphrey's McGee since Anchor Drops dropped in '04. I've had a few shows from that year on one form of portable media or another (Minidisc,...then iTunes/iPod,...shows are 2004-01-10 and 2004-01-30)
I've gotten back on the Archives and have been checking out some Umphrey's McGee from that year and am really enjoying the 2004-04-14 recording.

All the shows I've mentioned are available as Soundboards for free from the archive.org (search em out). You may need mkwact or dbpowerboost to convert them to something your player will play but they are worth a listen if you are into quality jambands.
Unfortunately I've only gotten to see them live once (Here in Spokane in 2009,...the only time they've played here) and while their new stuff is good I love the old classics,...2x2,...Fussy Dutchman,...Glory,...Slacker,...
If you're an UM fan suggest me some good shows,...I prefer soundboards but decent AUD recordings are fine (if they are two bassy or tinny sounding chances are I won't listen to them).
