I (Sister Young’n) is last track on side A on the album Fly! Fly! Fly! Fly! Fly! by Cecil Taylor.

The album features eight solo piano performances by Taylor.  The Allmusic review by Scott Yanow states “This solo album by Cecil Taylor is a little unusual in that he performs eight originals, some of which are quite concise; “T (Beautiful Young’n)” is only 53 seconds long. That is not to imply that the pianist’s music had suddenly mellowed with age but his lyricism is emphasized a bit more than usual and he sometimes sounds quite relaxed (without compromising his music) [source]
