Fans of online battle game League Of Legends have propelled a non-existent band to the top of the iTunes metal chart.

Pentakill features characters from the popular multi-player game, with very metal names such as Karthus the Deathsinger and Mordekaiser the Master of┬áMetal. The ‘band’ released their second album II: Grasp Of The Undying on Friday,and it immediately leapt to the top of the U.S. iTunes chart (currently sitting at #4) – and looks likely to debut in the top reaches of the Billboard chart. The single from the record currently has over 4.3m YouTube views.

Of course, where there is music, there are actual musicians involved. The band features Masterplan vocalist Jorn Lande, Battle Beast’s Noora Louhimo, ex-Nine Inch Nails member Danny Lohner, The Crystal Method producer Scott Kirkland, and one Tommy Lee on drums.

Lande, who voices Karthus, says of the album: “It’s great for a classic heavy rocker like myself to be a part of this modern gaming music world, and I’m excited and grateful for the opportunity to work with such a great team of talented people. This exciting development is not just about creating an original twist to the online gaming industry, but also about pioneering some groundbreaking new metal! My job is to make Karthus the singer he is, and add the classic heavy rock element to his performance. I’m proud that Karthus and his band are back to bring new Pentakill metal your way!”

Check out the record, below – and here’s hoping Mario and co. get the band back together and make a run at the charts very soon.
