Violinist Leroy Jenkins was one of the early members of the ground-breaking Association for the Advancement of Creative Musicians (AACM), founded in his native Chicago in 1965, and has remained on the leading edge of jazz since then. He will bring his new group Sting to Washington next weekend for performances at d.c. space Saturday and at Washington Project for the Arts Sunday. Two of the area's most innovative nonprofit arts support organizations, District Curators and WPA, are sponsoring the events. The Sunday concert is the first in a monthly series, New Music in the Afternoon, that will feature a talk by John Cage on Nov. 21. (Call 783-0360 or 347-8304.)

Jenkins spoke about his string- dominated combo (two violins, two guitars, bass and drums) from his home in New York: "Sting is a culmination of all the music that I've been playing, you know, since I started playing and writing. In the process of survival here I was giving lectures on jazz, starting with 1920 and up to the present -- Louis Armstrong, Zutty Singleton, Duke Ellington, Charlie Parker, John Coltrane -- and in the process of doing this it started creeping into my music. With Sting I'm able to use music in the tradition, but in sort of a changed-around or hybrid form. I want a string kind of jingle, a new sound that I could put this music that I wrote to, since everything I've listened to I've always tried to relate it to the violin."
