I'm pretty sure somebody still holds the original backing track, just wait. I remember this contest, one of the best contests MK ever did with the coolest prize, no stupid signed random given away guitars and all that BS. Record something, get acknowledged, meet MK — that's a contest we were all looking for! Also, the winner wrote a great article on a day of meeting MK, a very beautiful one. It wasn't for me though because I'm not a huge fan of electric guitars and especially copying solos over existing backing track.
