Music for me isn't so much about genre or style, instrumentation or production, but about feel. I've been equally moved by the Grateful Dead's segue from Help On The Way/Slipknot -> Franklin's Tower, Itzhak Perlman, Jackson Browne playing solo acoustic and the Concordia College (MN) Choir under the direction of Paul Christiansen. Each example touched a bit of the sublime, albeit with wildly diverse presentation and in wildly different environments. Whatever qualities those performances possessed - not quantifiable, of course - are precisely the qualities I strive for when I write and perform. Sometimes the magic works, sometimes it doesn't, as Chief Dan George (in the movie "Little Big Man) would say.
Here's an example of when the magic definitely works (for me, anyway!) - Jeffrey Foucault covering Bob Dylan's Señor (Tales of Yankee Power). Please enjoy!
