Otis Redding - I've Been Loving You Too Long
Memphis horns, both Booker T. and Isaac Hayes on keyboard/piano, and what I consider Otis's most stunning vocal performance. Yes, yes, my other option, "Try A Little Tenderness," features a performance that could be argued to equal or better it, but for my money, the tenderness (no pun intended) in this one, interspersed with true longing and yearning and sorrow and hope and ferocity...sigh. The build that starts around 2:10, while not as big and frenetic as "Try a Little Tenderness," to me is more emotional and moving. Those "ohs" that start at 1:50 and again at 2:10 make my heart sink into my stomach.
In deciding between the two, I also took into account that this one was co-written by Otis, instead of being a cover, and I think it reflects in the emotion he brings to it. He knows exactly what he meant when he wrote it and can bring that to the performance. Also, I took "Try A Little Tenderness" in the Rolling Stone Garbage List draft and am going in a different direction here.
My third choice was the under-appreciated "Down in the Valley," which, with this song and Otis's version of "Change is Gonna Come," forms my favorite three-song streak on any album, as the last three on Side One of
Otis Blue.
