Miles Davis Quintet Plays "'Round Midnight":
I've linked to a YouTube clip of the second Miles Davis Quintet before -- this was the famous quintet with Wayne Shorter, Herbie Hancock, Ron Carter, and Tony Williams that played together from 1964-1968. But last time the clip covered the band when they had just formed in 1964. Here's an excellent performance of the group playing late in their tenure; the tune is 'Round Midnight, and the place and time is Stockholm, 1967.
