The five-year association of keyboardist Merl Saunders and guitarist-vocalist Jerry Garcia was fruitful for both musicians, as well as for fans who witnessed their now-legendary performances as clubs in the San Francisco Bay Area. It made the venerable jazz organist and pianist an icon in the world of rock, and it opened new avenues of improvisation for the innovative rock guitar player. As Grateful Dead authority Blair Jackson points out in his booklet notes, Saunders helped Garcia expand his harmonic knowledge and even showed him some Art Tatum runs. "He taught me music," Garcia said of his friend. Well-Matched: The Best of Merl Saunders & Jerry Garcia finds the two musicians and an all-star supporting cast exploring a wide range of material, from rock and reggae to blues, R&B, and jazz, including a previously unissued treatment of Smokey Robinson’s "I Second That Emotion."
