My youngest son (age 24) is a major Umphrey's McGee fan, and has played me a good bit of their music over the last several years.
Finally agreed to go with him to see the band live last night at a venue here in Atlanta called the Tabernacle (beautiful old church converted into a concert hall).
Very impressed, great show! Super tight band. If they come around to your home town and you have not had the pleasure yet, check 'em out.
You can find a lot of their concert material on YouTube.
Anyone else out there in IORR land get your "Umph" on from time to time?
Cheers...
