I am with you Al, use as needed . . . Since I have pretty recently had to come up to speed fast on Chritian Rock, there are so many cases when the right backing track has made the difference. With the kind of sound they were wanting, and songs they were asking for, the arranger alone just didnt work for some songs. The congregation is very pleased with what i have been producing, whether it is live, arranger, or backing track. I am still playing along and singing, and hoping to add another vocalist soon!
Play on!
