The War On Drugs is a Grammy Award winning American indie rock band from Philadelphia, Pennsylvania, formed in 2005. The band consists of Adam Granduciel (lyrics, vocals, guitar), David Hartley (bass), Robbie Bennett (keyboards), Charlie Hall (drums), Jon Natchez (saxophone, keyboards) and Anthony LaMarca (guitar).

Founded by close collaborators Granduciel and Kurt Vile, The War on Drugs released their debut studio album, Wagonwheel Blues, in 2008. Vile departed shortly after its release to focus on his solo career. The band's second studio album Slave Ambient was released in 2011 to favorable reviews and extensive touring.

The band's third album, Lost in the Dream, was released in 2014 following extensive touring and a period of loneliness and depression for primary songwriter Granduciel. The album was released to widespread critical acclaim and increased exposure. Previous collaborator Charlie Hall joined the band as its full-time drummer during the recording process, with saxophonist Jon Natchez and additional guitarist Anthony LaMarca accompanying the band for its world tour. Signing to Atlantic Records, the six-piece band released their fourth album, A Deeper Understanding, in 2017, which won Best Rock Album at the 60th Annual Grammy Awards.
