METALLICA drummer Lars Ulrich told the San Francisco radio station 107.7 The Bone in an interview last month that the band has something coming up in December that will surprise fans. Asked what the group had in store for the immediate future, Ulrich explained, "There's a very interesting thing coming our way in December . . . There's another frontier heading in METALLICA's direction in December. Which, if anybody (at the band's management) even knew that I just said what I just said, they would hunt me down and silence me. But there is another frontier coming in December, which we're very excited about."During a roundtable with a group of journalists in London, England last week, Ulrich was asked for more clues as to what this "frontier" might be. "'Lulu Part 2' — just to piss everybody off!" he jokingly replied before adding, "I believe that there's an announcement on October 8. But don't hold me to that, I've been a little caught up in [the new METALLICA movie, 'Metallica Through The Never']. It's not anything of that magnitude… There may be a few of you that would be disappointed; it's not anything quite at that level." He continued: "I found myself telling one of your colleagues earlier, there's an IRON MAIDEN album called 'The Final Frontier'. So I'll borrow that from my interview an hour ago, and say, 'My clue will be the IRON MAIDEN album 'The Final Frontier'. There you go." During The Bone interview, Ulrich was also asked if the group planned to stage a third installment of its Orion Music + More festival in Detroit next year, after bringing the show's second edition there last June. The drummer replied, "Detroit was a great experience. We'd love to bring this thing back to Detroit. We've gotta sit down and look at the practical parts of it. And our good friends at (promoters) C3 (Presents) have gotta sit down and probably get their calculators out and all that stuff that we try to stay out of . . . It's not an easy thing to launch a festival, but we've had a lot of fun the last two years doing it, and we hope to bring it back to Detroit." Last June's Orion event drew at least 20,000 people per day over the course of two days to see METALLICA, RED HOT CHILI PEPPERS, DEFTONES, SILVERSUN PICKUPS, RISE AGAINST and more. "Metallica Through The Never" opened on 308 IMAX screens last weekend and earned $1.7 million, making it the biggest IMAX opening for a concert film ever. The movie, which expanded to more theaters on Friday (October 4), ranked 13th on the overall box office chart.
