The Selena Quintanilla estate has announced the release of Moonchild Mixes, a posthumous collection of songs featuring digital alterations of vocals the late Tejano singer recorded as a teenager. The album is due out August 26 via Warner Music Latina; the first single is a new version of “Como Te Quiero Yo a Ti.” Listen to the song below.

“Como Te Quiero Yo a Ti” was first released in 1987 on Selena’s sixth studio album Preciosa. A re-recorded version of the track was shared on the posthumous 2004 compilation Momentos Intimos. Moonchild Mixes also features 10 previously unheard recordings made when the singer was between 13 and 16 years old; her brother and bandmate A.B. Quintanilla told ABC News that he “cleaned” and re-timed Selena’s vocals, pitching her voice down “to make her sound a little bit more mature.” “What we’re doing is honoring her memory, her legacy,” he said. “We’re still going to do what we want with our music, with our sister, with our band.”

Selena was shot and killed by her former manager and friend Yolanda Saldívar in 1995. She was 23 years old. Her music and likeness has proved profitable for the family since her death—the estate has licensed her name and likeness for a MAC Cosmetics line, a Forever21 collection, a Funko Pop doll, even a debit card.
