Eric Johnson (born August 17, 1954) is an American musician, songwriter, and vocalist from Austin, Texas. Best known for his electric guitar skills, Johnson is also a highly proficient acoustic, lap steel, resonator, and bass guitarist as well as an accomplished pianist and vocalist.

Johnson has mastered a wide array of musical genres evidenced by the many different styles incorporated in both his studio and live performances including rock, blues, jazz, fusion, soul, folk, New Age, classical, and country and western.

Guitar Player magazine has called Johnson "one of the most respected guitarists on the planet". Johnson's stylistic diversity and technical proficiency with the guitar have been praised by Bill Hicks. His 1990 platinum-selling, full-length album, Ah Via Musicom, produced the single, "Cliffs Of Dover", for which Johnson won the 1991 Grammy Award for Best Rock Instrumental Performance.

Born into a musically-inclined family, Johnson and his three sisters studied piano and his father was a whistling enthusiast. Johnson started learning the guitar at age 11 and rapidly began progressing through the music that would heavily influence his future style, including Eric Clapton, Mike Bloomfield, Chet Atkins, Cream, Jimi Hendrix, Wes Montgomery, Jerry Reed, Bob Dylan and Django Reinhardt, among others. At the age of 15, he joined his first professional band—Mariani, a psychedelic rock group. In 1968, Johnson and the group recorded a demo, which saw extremely limited release; years later the recording became a prized collector's item.

He was a member of the Art Tatum Trio from 1943 to 1944, was a backing musician on recording sessions, and later led his own bands, including a recording session with Charlie Parker. He is notable for playing the tenor guitar, a four-stringed electric instrument.

Grimes was born in Newport News, Virginia, United States, and began his musical career playing drums and one-fingered piano. In 1938 he took up the electric 4-string tenor guitar. In 1940 he joined Cats and a Fiddle as guitarist and singer. In 1943 he joined the Art Tatum Trio as guitarist and made a number of recordings with Tatum.

He made four recordings with his own group augmented with Charlie Parker that are considered excellent examples of early bebop jazz: "Tiny’s Tempo", "Red Cross", "Romance Without Finance", and "I’ll Always Love You Just The Same", the latter two featuring Grimes' singing. He was one of the 52d street regulars.
