In this thicket Lil Wayne’s main error was in mistaking his blockbuster for a masterpiece. He performed about half of the songs from “Tha Carter III” — from the whimsical “La La” to the morose “DontGetIt” to a sometimes brutal, sometimes transcendent rock version of “A Milli” — making barely any distinction between hits and obscurities, or between these new songs and any of his others. He played songs from mixtapes (“Sky’s the Limit”) and ones he’s a guest on (DJ Khaled’s “We Takin’ Over”) with equal gusto. One of the night’s most invigorating moments was his impassioned delivery of his chorus from the Game’s “My Life.” Sometimes, when his own words ran out, he rapped someone else’s, like Jay-Z’s verse from “Mr. Carter,” and Tity Boi’s verse from Playaz Circle’s “Duffle Bag Boy,” on which Lil Wayne ordinarily only performs the hook.
