Over the history of the blues, there's been at least three different people plying their wares as Harmonica Slim, with one of them being far better known as Slim Harpo. But this Harmonica Slim was born Travis L. Blaylock down in Texas. He picked up the instrument around the age of 12 and was soon working as part of the Sunny South Gospel Singers gospel group, broadcasting over radio station KCMC in his hometown of Texarkana from the mid-'40s on. By 1949, he moved to Los Angeles, ingratiating himself into the burgeoning blues community, working package shows with Lowell Fulson and the like. He first recorded as a sideman on a group of dates in the mid-'50s for West Coast labels like Aladdin, Spry, and Vita. After spending most of the '60s working dates with Percy Mayfield, Harmonica Fats, B.B. King, T-Bone Walker and others, Slim finally got to record a full album under his own name for the Bluestime label in 1969.
