Willie Brown was a close friend of Son House. Together in 1931 they traveled with Charlie Patton and Louise Johnson to Grafton, Wisconsin to record for Paramount Records. This recording session produced some of the seminal performances of the Delta Blues. Willie played behind Patton on several songs and only recorded two solo pieces: "M&O Blues" and "Future Blues".
"M&O Blues" in played in the key of E. It is a very well thought out guitar arrangement that compliments the vocal line. The opening phrase presents a Delta lick that is heard with variations in the playing of Son House, Charlie Patton and Tommy Johnson.
