David Gilmour has premiered his new single “Rattle That Lock,” the title track off the Pink Floyd guitarist’s upcoming solo LP boasting an uptempo bass groove, rousing choir and lyrics drawn from John Milton’s Paradise Lost. As Gilmour previously revealed, the melody was inspired by “four notes, created by [sound designer] Michaël Boumendil, which precede announcements at French SNCF railway stations which David recorded on his phone at Aix-en-Provence station.”
