Josh Groban will release his fifth studio album, Illuminations this Friday, November 19. On it, the Grammy nominated singer teams up with veteran producer Rick Rubin, known for his work with Metallica, Red Hot Chili Peppers, Johnny Cash and Dixie Chicks.

Also featuring on the 29-year-old LA native's new album is Irish singer-songwriter Declan O'Rourke's, 'Galileo', which appeared on the Galway man's debut, Since Kyabram.

Groban says of the song: "'Galileo' appealed to me because I though the melody was so beautiful... It represents the natural beauty of falling in love and of your view of the world and the universe when that happens and the bigger picture that it brings you".

Here, O'Rourke performs the track at the Hot Press Music Show, 2008:
