The first half of this week is rife with top-notch options for concert-going music lovers, with three international acts hitting our city. First, on Monday (Jun. 8, 19:00), the recently reunited riot grrrl legends of L7 are playing at Zitadelle in Spandau, opening for ex-Gun n’ Rose Slash. Speaking of metal, if you thought the 2011 Farewell Tour of Judas Priest (pictured) was for real, you’ve got another thing coming. Namely, another tour. Gay singer Rob Halford and company will rock Arena in Treptow (Jun. 9, 20:00). Bringing the three-day bender to a close will be the queer Canadian hipsters Austra, returning to Berghain with their dreamy goth-pop soundscapes (Jun. 10, 21:00).
