Then based in Philadelphia, Hartley began working on his own music in earnest when the War on Drugs album Slave Ambient was taking longer than expected to complete. His first Nightlands album, Forget the Mantra, arrived on Secretly Canadian in late 2010. Though his duties with the War on Drugs -- who released Slave Ambient on the same label in mid-2011 -- kept him busy for much of the following year, he also issued the All the Way and Covers EPs, the latter of which included a gorgeously hazy version of Lindsey Buckingham's "Trouble." In January 2013, Hartley delivered his second Nightlands album, the emotionally nostalgic Oak Island. It featured contributions from the likes of Heather Woods Broderick, harpist Mary Lattimore, and Nick Krill (Teen Men) in addition to members of the War on Drugs including Adam Granduciel (on guitar) and Robbie Bennett (Arp Omni, Juno, keyboards).
The War on Drugs had a critical and commercial breakthrough in 2014 with Lost in the Dream and signed with Atlantic Records. Hartley didn't abandon Nightlands, however, releasing the project's third LP, a set of spacy love songs called I Can Feel the Night Around Me, on Western Vinyl in May 2017. It was recorded mostly alone in a basement rehearsal/storage space formerly used by his band.
Hartley became a father and relocated to Asheville, North Carolina, before recording Nightlands' next long-player, July 2022's Moonshine. It featured a number of remote collaborators, including four of his War on Drugs bandmates, Frank LoCrasto (Cass McCombs, Fruit Bats), and producer Adam McDaniel (Angel Olsen, Hurray for the Riff Raff). ~ Marcy Donelson & Heather Phares, Rovi
