I went to an MCGC (Michigan Color Gaurd Circuit) indoor drumline show last year (and will hopefully be going to more this season to get some video. Wasn't too impressed with any of the shows besides NorthCoast Academy's "Echo." Everything else bordered on boring because there was nothing new to me. Here is a poor quality video of "Echo" I took. Hopefully will get more, higher quality videos up when I get a new computer. Enjoy.
I heard about another group today that is doing an all Radiohead show. That is awesome. Here is their website: http://onyourvideotape.com/
I could do without the singing but this show overall is pretty cool because they've done a few things I haven't seen before, plus that snare solo at the end is pretty sweet. And I love that they squeezed in part of "Let Down" as that is one of my favorite songs of all time.
