The date of this set is uncertain. The Davis Quintet was booked at the Plugged Nickel from June 4-14 (Wednesday-Saturday), with a break on Monday-Tuesday, June 9-10. One of the concerts was reviewed in Down Beat (August 7, 1969), where reviewer Larry Kart remarked, "Outside of Charlie Parker's best units, I don't think there's ever been a group so at ease at up tempos as Miles Davis' current quintet. Their relaxation at top speed enables them to move at will from the 'hotness' up-tempo playing usually implies to a serene lyricism in the midst of turmoil."

The Quintet was busy throughout the spring and summer of 1969, including three appearances at the Village Gate: April 25-26, May 23-24, and July 29-August 10.
