Two albums were assembled from the concert recording. The up-tempo pieces were issued as Four & More, while My Funny Valentine consists of the slow and medium-tempo numbers. Davis biographer Ian Carr notes that the former were "taken too fast and played scrappily", while the Funny Valentine pieces "were played with more depth and brilliance than Miles had achieved before."[5] He goes on to laud the album as "one of the very greatest recordings of a live concert … The playing throughout the album is inspired, and Miles in particular reaches tremendous heights. Anyone who wanted to get a vivid idea of the trumpeter's development over the previous eight years or so should compare [earlier recordings of "My Funny Valentine" and "Stella by Starlight"] with the versions on this 1964 live recording."[6]
The hurried nature of the faster pieces that night has been partially attributed to the sheer importance of the event weighing on Davis's young rhythm section, who were playing their biggest date yet. Tensions were only worsened by their anger on finding out they would not be paid for the performance. Pianist Herbie Hancock, twenty-three years old at the time, later described the psychological pressure on the quintet:
"That was my first time playing at the Philharmonic Hall and that was, like, a big deal, because the new Carnegie Hall was the Philharmonic Hall. Just from the prestige standpoint I really wanted to play good—the whole band really wanted to play good because that was the whole band's first time playing there … although Miles had played at Carnegie Hall before … but it was really a special concert. Only the New York Philharmonic plays there … and I tell you something … it was really funny … when we walked away from that concert, we were all dejected and disappointed. We thought we had really bombed … but then we listened to the record - it sounded fantastic!"[7]
