I saw Mother's Finest at the Six Flags outdoor amphitheater when I was in high school 1981. I was sitting on the hill that surrounded the concert area when it started. They turned off the lights; then all you heard was one solid low bass note. The sound built until the whole hill was vibrating. Then as the thrumming from that note reached a crescendo, there was a kick beat from the drums and the stage blazed to life into 'Piece of the Rock' !

I jumped up and started making my way though the crowd to the stage edge, cause I just had to see this group up close. It was stellar !
I was close to one side so I could see Wyzard doing his thing on the bass and get a good view of Baby Jean strutting her stuff ! That concert changed my musical life. I didn't realize it at the time, but I think that's why I got interested in the Bass.
