DC Comics has entered into a deal with Milan-based gothic heavy metal band Lacuna Coil, with two specific offshoots so far. The first is that Batman will appear on stage in their 2020 tour, in an officially licensed capacity.
The second is that the Dark Nights: Metal series by Scott Snyder and Greg Capullo, currently being published on Italian newstands is getting a variant cover. For the recent Lucca convention in Italy, the Italian licensor published a variant of Metal with a cover by Giuseppe Camuncoli and Riccardo Burchielli, featuring the band and the Batman Who Laughs.
The edition was published as below and in ashcan form. The comic has a double-page spread featuring the Dark Dimension Batmen and Lacuna Coil playing alongside them, as seen below. Copies are selling for around 13-15 Euros on eBay.
