"Muhal Richard Abrams hasn't presided over many small combos with a more imposing lineup than on this 1977 session. Anthony Braxton and Henry Threadgill played numerous instruments from alto, tenor and soprano saxes to flutes and clarinets, even adding background vocals. Fiery percussionist Steve McCall and bassist Leonard Jones, who also added some vocals, completed the lineup. The unit made demanding, harmonically dense and rhythmically unpredictable material, with Braxton's scurrying solos ably matched by Threadgill's bluesier lines and Abrams' leadership and inventive blend of jazz, blues, and other sources holding things together.
