Around '75 when the recession hit, club owners started going to disco because it was cheaper for them to just buy a sound system than it was to hire a band.
I was born in Alabama and my first live music experiences were in church. Every Sunday we watched regional gospel groups on television singing their hearts out.
On acoustic guitar I tend to stay in the key of D for some reason. On electric guitar I keep basic: C, G, D, and A. The key of D minor is also real good for me.
