Metallica takes over the Sphere for a two-night run, pairing decades of thrash metal anthems with the venue's wraparound LED visuals and immersive sound for a show unlike anything the band has done in a traditional arena. Over at T-Mobile Arena, Nickelback brings its catalog of radio-ready rock hits to the Strip, with pyrotechnics and big screens built for a crowd that knows every word. For something more intimate, Chicago continues its residency at The Venetian Theater, running through brass-driven classics like "25 or 6 to 4" and "Saturday in the Park" alongside the horn-powered ballads that carried the band through the '80s, all in a room small enough to feel every note.
