Ten Years (EP)

Ten Years is the first extended play (EP) by American pop duo Aly & AJ. It was released on November 17, 2017, and Ten Years marks their first release in ten years, following their third studio album, Insomniatic (2007), which peaked at number 15 on the Billboard 200. It is also their first release since leaving Hollywood Records in 2010; the record was released on their own label, Aly & AJ Music, LLC.

Departing from their previous commercial pop rock sound, Ten Years features a 1980s-inspired musical composition incorporating echoed vocals, an 808-inspired drum machine, and synth pads. The EP was preceded by the release of two singles: "Take Me" and "I Know". Ten Years received positive reviews from music critics, who praised the blend of 1980s-inspired music and modern production, as well as the duo's songwriting. The album peaked at #25 on the US Independent Albums chart. The EP was further promoted by the Promises Tour, which the duo undertook through July 2018.

A deluxe version of Ten Years was released on November 30, 2018, and included the release of the single "Good Love".
