If you're gonna get excited about tracks, we have to talk about delay pedals, 'cause that part of the music is not being played in real time. Or loopers - same thing. Tracks can be useful. They can also be abused. If you're going to play with tracks, it actually takes more discipline to do it well than playing without tracks. We do it in church, but in the churches I play in, we are all very well rehearsed.
