ABC/Randy HolmesWhat’s Metallica up to? The metal legends are teasing an announcement, which will be made this Monday, February 26. As for what the announcement will be about, some have speculated it could be another round of U.S. tour dates. Another possibility could be an …And Justice For All box set, which would be the next album in Metallica’s ongoing reissue series. Or maybe the announcement will be a whole new album, but that seems very unlikely.
