In the transcription of "While You Were Out" there is a part where Steve put in the indication "No Meter". I copied that piece, and I remember Frank laughing and commenting on that when I showed it to him. He let it go in that way, but he said "What's that supposed to mean? Everything's in some meter". I think he felt that Steve had sort of copped out on that one. It was clear to me then that, at least for Frank, the meter was an underlying reality, and it didn't make much sense to him to think about his music without it, even if it was an improvisation with no apparent groove.
