was a talented guitarist on the level of a Barney Kessel
or Herb Ellis
, who spent most of his career playing commercial music in the studios. Shortly after he moved to Los Angeles in 1950, Roberts
was firmly established in the studios, although on occasion he recorded jazz (most notably twice for Verve during 1956-1959, a Concord session from 1977, and one for Discovery in 1979); however, most of his other output (particularly for Capitol in the 1960s) is of lesser interest. The co-founder of the Guitar Institute of Technology in Hollywood, Roberts
was an enthusiastic and talented educator, and wrote a regular instructional column for Guitar Player.
