This cover version released in 1961 on the album of the same name, is one of 'Trane's best known works.
It was played on a soprano sax, known for it's shrill high pitch sound. Considered an obsolete instrument in Jazz by this time, Coltrane picked it up and somehow if it wasn't for that sax, the song would not have that feel or character.
The piano work of McCoy Tyner is superb too... the whole song has a dark, moody tone unlike the original off the "Sound of Music". This song is an experiment in modal jazz through popular song.
Have a good weekend everyone...
