Zaki captures the Oliver Lake Trio live at the 1979 Willisau Jazz Festival. Lake was also performing at the festival as a member of the World Saxophone Quartet and was asked to have his trio, which had been performing together for about three years, participate as well. This trio, sans bass, features Michael Gregory Jackson on electric guitar and Pheeroan Aklaff on drums. Throughout the 78 minutes of spontaneous free jazz, many risks are taken, sometimes rewarding, occasionally repetitious. This is especially the case on the nearly 24-minute "Zaki," which loses the thread about halfway through. Lake triples between alto, tenor, and soprano saxophones.
