Judicanti Responsura is the Los Angeles based duo of tubaist William Roper and percussionist Joseph Mitchell. They have known each other and performed together since 1969. The ensemble was formed in 1984 and is focused on music of our time, with a special emphasis on compositions that require improvisation. The ensemble's repertoire includes works by its members, commissioned works, jazz standards and some contemporary classical compositions. Mr. Roper's use of alto to contrabass ranged brass instruments and Mr. Mitchell's abilities on melodic percussion, in addition to indefinite pitch instruments, gives the ensemble an unexpected versatility.

Joseph Mitchell, performer, teacher, and composer has released two recordings as a leader. He has performed with Aretha Franklin, Gladys Knight, Lou Rawls, Marilyn McCoo, the L. A. Philharmonic, Pacific Symphony, Pasadena Symphony, and Hollywood Bowl Orchestra. He is on the faculties of Los Angeles City College, El Camino College, and Cal State University, Dominguez Hills.

William Roper, tubaist and composer, has released 10 recording projects as leader or co-leader. He has worked with a wide range of artists including Wadada Leo Smith, James Newton, Horace Tapscott, Yusef Lateef, Bobby Bradford, Anthony Braxton, Vinny Golia, Francis Wong, Glenn Horiuchi, and others.

Judicanti Responsura originally performed transcriptions and the few published works for tuba and percussion. It's members soon began composing their own works and commissioning pieces. Judicanti Responsura is an improvising ensemble that embraces African American improvisational traditions. In their own compositions, they seek seamless transitions between written and improvised material. Judicanti Responsuraís repertoire includes purely instrumental works, works with voice, spoken word, electronic media and multi-disciplinary works. The ensemble is represented on six recordings on the Asian Improv, Tomato Sage Consortium and Heliotrope Dreams labels. Judicanti Responsura's members were raised in Los Angeles' African American neighborhoods and were somewhat politicized by the experience. Much of our music reflects that politicalization in its inspiration, its titles, its content, our wardrobe and where we chose to perform.
