“Starless” by King Crimson
King Crimson have a knack of releasing long songs. Their longest song Lizard (divided over four parts) didn’t make our list, but the 12 minutes and 16-second long Starless did. It was featured in the album Red Album, released in 1974, not too long before the band disintegrated.
John Wetton wrote the lyrics and composed the melody for the song. The song was initially intended to be a part of the band’s previous album, but Bill Bruford and co. weren’t very fond of it at the time.
