Metallica takes over the Sphere for a two-night run that wraps the band's thrash-metal catalog in the venue's massive wraparound screens and immersive sound, turning decades of riffs into something closer to sensory overload. Over at T-Mobile Arena, Nickelback brings its arena-rock hits and big production—pyro, LED screens, the works—for a night built around singalong choruses and Chad Kroeger's gravelly vocals. That same arena also hosts the Sweet 16 and Elite 8 of the NCAA Women's Basketball Tournament, with four teams fighting through two days of single-elimination games for a Final Four spot, drawing alumni, band sections, and curious locals into one tense, loud weekend of March Madness.
