AJ and Aly Michalka are planning a pop comeback as 78Violet.

The duo is set to perform its first live show in five years later this month (Jun13) under the new moniker, and a debut single, Hothouse, will be released in July (13).

Announcing the big return in a press release, the Michalkas state, "We couldn't be more ready or excited to introduce our amazing fans to the new and evolved sound behind 78Violet."

The sisters will perform at the Roxy Theater in Los Angeles on 26 June (13) and they have a show lined up at the Gramercy Theater next month.

AJ and Aly, who enjoyed hits with Potential Breakup Song and Into the Rush, turned their backs on music in 2009 and followed their acting dreams - Aly will appear in the upcoming film Grown Ups 2, while AJ had small parts in Super 8 and The Lovely Bones.
