METALLICA, LINKIN PARK and LIMP BIZKIT will officially announce their tour this afternoon (Feb. 5) at a press conference to be held at El Rey Theater in Los Angeles. The tour, as first reported on Friday (Jan. 31), will head out this summer playing stadiums. Full details of the summer trek will be announced, as will the first round of dates.Before embarking on the monster tour, METALLICA will appear at a number of European summer festivals, while LINKIN PARK will head out on their own arena tour with JURASSIC 5 and MUDVAYNE. It is presently unclear if LIMP BIZKIT will undertake a headlining tour of their own prior to hooking up with METALLICA and LINKIN PARK in the summer. METALLICA are currently in the studio finishing up the tracking process for their new album, tentatively due in June. LINKIN PARK's sophomore effort, "Meteora", is set for a March 25 release, while LIMP BIZKIT's latest, "Less Is More", is expected to surface in April.
