Andrew Paine of Billboard.com reports that the Sonisphere cinecast from the Sofia, Bulgaria leg of the touring rock festival was seen by more than 100,000 fans, according to promoter Stuart Galbraith.

The global June 22 cinecast featured the "Big Four" of 1982 thrash metal — METALLICA, SLAYER, MEGADETH and ANTHRAX — and was beamed via satellite in HD to cinemas. It was distributed globally into hundreds of cinemas by New York-based BY Experience.

In the U.K. it was screened in 79 cinemas. "At the Odeon in Leicester Square in London there was a mosh pit, and at the end of the show they had a stage invasion, which is just phenomenal to even think about," says Galbraith. "Not only are we hitting the territories that we're playing with this tour, [with the cinecast] we've taken the Big Four and Sonisphere into countries we haven't been able to get to this year."
