In 1966, the late Steve Lacy visited the new ESP-DISK office at 156 5th avenue with a master tape of his concert in Buenos Aires with his quartet, Louis Moholo, Enrico Rava and Johnny Dyani. He offered to sell the master for what I thought was an exorbitant price. I bought it. This LP was released featuring a reproduction of a painting by his friend, the late Bob Thompson, who had died before obtaining recognition. In 1992, the master tape was brought to engineer Ken Robertson at the Sony Studio, who observed that it had been recorded out of phase, and he corrected the phasing. - Bernard Stollman Digitally remastered from the original tapes Featured Artists Steve Lacy: soprano saxophone Enrico Rava: trumpet Johnny Dyani: bass Louis T.
