Escapist, lush synth-pop with nods ‘70s California. For their third album, Empire of the Sun tapped a dream team of legendary musicians to lend their talents: Henry Hey and Tim Lefebvre from David Bowie’s Blackstar band, Prince bandmate Wendy Melvoin, and Fleetwood Mac’s Lindsey Buckingham. The latter helped write “To Her Door,” which is as warm and wistful as Fleetwood’s “Gypsy” or Empire’s own “Walking on a Dream.”
