Next month, art-music master Brian Eno will release The Ship, his first solo album since 2012. The LP only has two songs, both of them crazy long. This morning, Eno shared the album’s 21-minute title track, the first of those two songs. The expansive, drawn-out track is built out of glacial waves of synth and Eno’s newly gravelly, heavily processed lower-register voice. Below, listen to the song and read some words about it from Eno.

Eno says:

The piece started as an Ambient work intended for a multi channel sound installation in Stockholm, but during the making of it I discovered that I could now sing a low C — which happens to be the root note of the piece. Getting older does have a few fringe benefits after all. From that point the work turned into an unusual kind of song… a type I’ve never made before where the vocal floats free, untethered to a rhythmic grid of any kind.

The Ship is out 4/29 on Warp.
