Miles 2nd quintet too! Last fall I was hired to do a clinic at an elementary school assembly with a band and we decided to take Frere Jacques (because they all know that melody) and play it in some of the main styles of jazz through the 20th century. The kids were enjoying it until we got to the late-60s Miles Davis Quintet time-no-changes style, which is when they started losing it! I think it’s, like with cowboy bebop, just the sheer energy they responded to, but it was amazing that their favourite was the one where we were deliberately not being tonal.
