Alphabetizing is according to the preference of the individual; trombonists may be listed under maiden, married, or both last names.
That's Annie Whitehead (above), described by Beat International as "The Sly and Robbie of British brass,the woman everyone turns to when they want a class trombone player."
She has worked with many well known artists including Joe Jackson,Elvis Costello, Joan Armatrading,Chis Rea, The Style Council and Jah Wobble's Invaders of the Heart.She is well known on the international Jazz scene and was a member of Chris MacGregor's Brotherhood of Breath and the Carla Bley Very Big Band. She also tours regularly with the Penguin Cafe Orchestra and Jasper van't Hof's Dutch/African group Pili Pili. She is also a member of "Rude" with Ian Maidman, Liam Genockey and Harry Beckett . Currently Annie has her own band "The Annie Whitehead Experience".The line-up is Annie on trombone,Ian Maidman on guitar, Steve Lodder on keyboards, Steve Lamb on bass and Liam Genockey on the drums.
Once, I dreamed of being a go-to "class trombonist" listed in teh European Free Improvisation yellow pages. I even met Annie's heroes Frank Rosolino and J.J. Johnson at an International Trombone Association convention in Salt Lake City when I was fourteen.
If professional women trombonists banding together on the Web doesn't count as a prime example of karass discovery, I don't know what does.
