It's a tribute to Beyonce's skills as a performer that this album from her 2009-2010 tour is a bit boring. Like the best live albums, it just makes you want to actually be there. B knows what fans want: Fierce performances. And she delivers, singing her guts out in a musical retrospective, from massive hits to classics, from "Ave Maria" to a roof-shaking recap of her inaugural-ball take on "At Last." It's backed by a live band, features appearances by Kanye and Jay-Z and crackles with energy and emotion (we dare you not to tear up at "Halo" as a potentially cheesy Michael Jackson tribute).
