Neil Young reunited with Crazy Horse and the first song from their first album in seven years is closer than you might expect. In fact, the legendary musician announced that 'Rainbow for Colors', the first single from Colorado, will be released later this month.

Young made the announcement on his website, writing: "Billy, Ralphie, Nils and I are all very happy to bring this song 'Rainbow of Colors' to you in all its ragged glory, as my original producer and life-long friend, the late David Briggs once said."

The single announcement comes after Young described the upcoming album with Crazy Horse as "one of the most diverse albums" of his career. Colorado consists of "10 new songs ranging from around 3 minutes to over 13 minutes" and will be out in October.

Young also revealed in the post that he's working on a documentary depicting the making of the album called Mountaintop Sessions. "It is a wild one folks, no holds barred. You will see the whole process just as it went down! Worts [sic] and all! I don't think a film about this subject with the openness and intensity we have captured has ever been seen", he proclaims.

The documentary will be released in over 100 cinemas world-wide in the same week Colorado hits the shops. Colorado will be available digital, on CD and as a double vinyl including an exclusive 7" single.

Neil Young has been working with Crazy Horse since 1969 when they released Everybody Knows This Is Nowhere. Their last joint record was 2012's Psychedelic Pill.

Previously, Young joined Bob Dylan and Glen Hansard on stage in Kilkenny. Read the full Hot Press live report here.
