San Francisco Bay Area native Jules Rowell first began playing music on the violin in the 1950s. During high school, his music instructor encouraged Jules to play the valve trombone, which he has done ever since.

In addition to a master's degree in music from San Francisco State University, Jules has put in several years of study at the Berklee College of Music in Boston, Massachusetts.  He has literally taken hundreds of private lessons with such symphonic performers as Will Sudmeier and Ned Meredith and with jazz artists Phil Wilson and Don Doane.

Jules has spent time touring the nation and the world with the orchestras of Woody Herman and Ray Charles, while those gentlemen were both still alive. He has also performed with the innovative Latin rock bank Azteca, for which he recently took part in the making of a documentary on Union Film (released August 2008) in Los Angeles.

Jules has also performed with such artists as Eddie Palmieri, Francisco Aguabella, Woody Shaw, Tom Harrell, Joel Dorham, Lenny White, Eddie Marshall, Art Lande, The Supremes, Bobby Vinton, Tony Bennett, Ed Kelly, Bert Wilson, Sonny Simmons and The Joe Henderson Memorial Orchestra led by Warren Gale, Jr.

In addition to winning the first and second places in the 1999 John Lennon Song contest, Jules has composed and arranged material for Pete Escondido, Mark Little, Louie Romero and Masacote, The Hot Club of San Francisco, the Kronos String Quartet, the Mike Vax Orchestra, and Francisco Aguabella.

Jules is currently co-leading the Fairweather Band with percussionist Bill Belasco. This is a musical project which highlights and pays respect to the great compositions and vocal styling of legendary jazz trumpeter Kenny Dorham.
