The Brothers Johnson , George aka 'Lightnin' Licks' and Louis E. Johnson aka 'Thunder Thumbs', achieved their greatest success from the mid-1970s to early '80s, with hit singles like "I'll Be Good to You", from their debut album, Look Out for Number 1.

For a short time, the Brothers Johnson backed such touring R&B acts as Bobby Womack and the Supremes.  They joined Billy Preston's band, and wrote "Music in My Life" and "The Kids and Me" for him before leaving his group in 1973.
The eventually started doing separate ventures.  Louis played bass on Michael Jackson's Thriller LP and recorded a gospel album, and George worked with Steve Arrington.  Their mid-'80s return LP Out of Control; was produced by Leon Sylvers produced.  Although it didn't equal their past success, it did get them another R&B hit with "You Keep Coming Back" in 1984.
The duo split up in 1982 and both had brief solo careers.
