I understand YJ was nominated for a grammy in the same category as Pat Metheny?? If so, I think YJ was much more deserving of the award from the musical aspect, even though they don't have as large a fan base as Metheny.
I am a recent fan of YJ, listening to their Priceless Jazz collection and Blue Hats CD's, both of which are great. Their ability to pull off the traditional jazz sound as well as the more contemporary 'electric' jazz is really impressive.
