In fact, the area’s likely to be a madhouse of activity, with hordes of people checking out the Final Four Fan Fest at the Phoenix Convention Center or just hanging out and soaking up the vibe. And then there’s the tens of thousands that will flock to the March Madness Music Festival up at Margaret T. Hance Park, one of the biggest events of the weekend not involving sporting equipment. After all, the weekend-long event, which is comprised of three separate outdoor concerts at the park, boasts a blockbuster lineup of bands and musicians, many deserving of legend status.
