As the heart of the rhythm section, the bass is the center of any jazz ensemble and, in ways, the most important of the jazz instruments. It is, therefore, something of an irony that jazz bassists are known not so much for their own performances as for the horn players and pianists with whom they share the spotlight. With this measure in mind, Bob Magnusson must be counted as one of today's most successful jazz bassists. He has performed with the likes of Art Pepper, Slide Hampton, and some of the other greatest names in jazz. In addition, he has performed occasionally with such pop stars as Natalie Cole, Neil Diamond, and Linda Ronstadt. An examination of his discography alone, with more than 150 recording credits, would be exhaustive. Magnusson speaks of these achievements in an almost off hand manner as though it were a commonplace thing to perform with Benny Golson or Mark O'Connor.
