In the wee hours of a warm November morning, a piercing sound fills the cramped control room of Studio C at Miami's Hit Factory. Wreathed in smoke, with a long spliff hanging from his lips, Lil Wayne rocks back and forth, staring intently at the fingers of his left hand as they dance across the neck of a blue Gibson electric guitar. He plucks the strings with his right thumb as he tries to wheedle out licks to go with the thick, thumping beat he laid down earlier. After several minutes of noodling, Wayne removes the blunt from his mouth and exhales plumes of smoke through his nose.

"Mwah, mwah, mwah, mwaaaah," he sings, mimicking the sound of the instrument. "That's how I learned to play," he says. "I match the guitar to my mouth."

Wayne first picked up the guitar about two years ago and boasts that he's never had a lesson. Critics have variously described his playing as "embarrassing," "incredibly bad," "awful," and, somewhat more charitably, "unstudied." Tonight, his vaguely bluesy refrains are drenched in spacey feedback and mostly feel like the work of a very stoned jam-bander playing an untuned guitar with the wrong hand. Weezy doesn't care. "Now at my shows, I get to play like John Mayer," he says, running his thumb over the strings. "The crowd goes crazy when they hear that. When I even just walk by the guitar onstage, they scream. When I grab it, they scream. When I sit down and play, they hush. And when I finish, they scream."

You can't argue with results, and if there's one thing the 26-year-old Dwayne Michael Carter Jr. has produced a lot of in 2008, it's results. His year got off to a rocky start when he was hit with felony charges in January, after border police in Arizona found weed, coke, Ecstasy, and a .40 caliber pistol on his bus. (He pleaded not guilty and is awaiting trial.) It wasn't his first brush with the law, and it hardly seemed to throw him off stride. In April, "Lollipop," an addictive, throbbing nugget of Auto-Tuned erotica and the leadoff single from his sixth album, became Wayne's first No. 1 hit and transformed him from hip-hop's most respected MC -- the justifiably self-proclaimed "best rapper alive" -- into someone your mom might recognize on the street. Two months later, he released Tha Carter III, technically his first album in nearly three years (more on that later), selling more than 400,000 copies on its first day and more than a million in its first week. In late October, he added another Carter III to his stat sheet, when he was on hand in a Cincinnati delivery room to witness the birth of his son, Dwayne Michael Carter III ("It was very nasty, but beautiful at the end," Wayne says), whose imminent arrival he'd announced to the world just a few days earlier while collecting the MVP of the Year trophy at the BET Hip-Hop Awards.
