On Sept. 9, the site of the attack will reopen with a huge benefit concert, We Are Manchester, that will raise money to fund a memorial for the victims, according to Billboard.
Gallagher tweeted out an announcement on Wednesday via Twitter. The statement also noted that tickets for the show will go on sale on Thursday, August 17.
Astley, too, tweeted out an alert about the concert, saying: "Proud to be part of the re-opening of @ManchesterArena on 9/9. All proceeds go towards the Manchester Memorial Fund."
We Are Manchester will be the second major concert held in honor of those who lost their lives during the horrific attack in May. The first, One Love Manchester, was put together by Grande and featured performances by Katy Perry, Miley Cyrus, Justin Bieber, Chris Martin, and Imogen Heap. The proceeds from the show contributed greatly to the We Love Manchester Charity, which has raised approximately $23 million.
Billboard notes that nine people impacted by the blast are still hospitalized and that the investigation into the suicide attack is still in progress. Since the attack, many shows have been canceled, including those by Kings of Leon, Radiohead, and Blink-182.
