Metallica brings its thrash-metal firepower to the Sphere for a two-night run, pairing the band's double-kick-drum assault with the venue's wraparound LED visuals for a sensory experience unlike any arena show. Over at T-Mobile Arena, Nickelback rolls through with decades of radio-ready rock anthems, backed by pyrotechnics and massive screens built for singing along at full volume. For something a little more laid-back, Chicago settles into its residency at The Venetian Theater, bringing horn-driven classics like "25 or 6 to 4" and "Saturday in the Park" to an intimate room where the band's brass hits harder live than on record. Together, these shows cover heavy riffs, arena-rock hooks, and brass-powered classics all in one trip to the Strip.
