Jack Antonoff and Lana Del Rey have been constant collaborators for years, with Antonoff co-producing and co-writing Del Rey's albums Norman Fucking Rockwell! and Chemtrails over the Country Club. Now that Antonoff is readying a new album called Take the Sadness Out of Saturday Night with his rock act Bleachers, Del Rey is joining him for "Secret Life," the project's latest single. A little bit Elliot Smith and little bit Brian Eno, "Secret Life" is a gentle acoustic guitar-driven plea for companionship with Del Rey on background vocals. Listen below. Take the Sadness Out of Saturday Night drops Friday, July 30.
