Mark Levinson worked as the bassist for jazz pianist
Paul Bley (in 1966 through 1971 by his own account), and mentions other renowned jazz musicians with whom he played then. Bley's memoir has a 1965 photo of his trio with Levinson and
Barry Altschul, and tells of touring and recording in Europe with them in 1966. Bley describes Levinson and Altschul as "a rhythm section with a wide range of talents". Levinson won the case in 1986 but lost the right to use his name as a
trade name on an audio product. For this reason, since several years before the lawsuit, "Mark Levinson" branded audio products have had no relationship to the brand's founder; the "Mark Levinson" brand name has been and continues to be an
intellectual property wholly owned by
Harman International. In resolving the case, the
Second Circuit Court of Appeals wrote a 25-page decision that outlined the rights of entrepreneurs who use their own name as the name of a company. Levinson himself has continued to work in the industry, creating several new companies. Levinson ran his second company, Cello Ltd., from 1984 to 1998. With Cello, Levinson created high-priced models such as the Audio Palette. In 1999, Levinson founded Red Rose Music, an audio company with its own New York retail store on
Madison Avenue. The business model of Red Rose was to create compact, affordable products with very high-quality sound. In 2007, Levinson moved to Switzerland and used his consulting revenue to finance the founding of
Daniel Hertz S.A., an audio equipment and audio software company. ==Personal life==
