Exclusive: Lil Wayne Logs ’15-Hour’ Post-Prison Studio Session.

In addition to confirmations to MTV News from the Young Money camp, a photo emerged that shows Weezy hard at work in the booth; the image was snapped just moments after he began a session at Miami’s legendary Hit Factory studio.

Young Money president Mack Maine confirmed the session, tweeting, “It’s official Wayne laid his 1st verse!!!! Torture!!!! YMCMB.”

Videographer DJ Scoob Doo, who joined the New Orleans MC in the studio, shared exclusive details with us: “Wayne picked up right where he left off with a 15-hour recording session of nonstop work. Day two is tonight, and expect more therapy for a game that needs help.”

Scoob first began tweeting about the session on Monday night: “Guess Who Is On The Way To The Studio????” He followed that tease with another post, writing, “The Studio is Like A Library 2NITE … Nothing But HISTORY!!!!!!” and “Nino Brown 1st Studio Session Since Rikers Island 2NITE.”

Scoob will be providing MTV News with regular updates on Wayne’s progress in the studio. Meanwhile, he kept the teases coming, with an offer of a prize to whoever could figure out how many songs were on deck to be recorded.

In the photograph, Wayne, sporting a blue fitted cap, appears hunched over what appears to be a pad of paper. The writing material is significant, since the New Orleans MC has long had a reputation for committing his verses to memory.

The day before his release from Rikers, Young Money president Mack Maine revealed on “RapFix Live” that an extended sentence had led Wayne to begin putting his lyrics to paper.

“He’s writing. He’s writing music now. Everyone knows that Wayne didn’t write before he went in,” Maine said. “[He’s been] incarcerated for eight months. You can’t remember eight months of material up top.”

It was still unclear at press time exactly what tracks Wayne was working on, but his frequent collaborators have said they’ve prepared plenty of beats for him to choose from. Cool of Miami-based production duo Cool & Dre told MTV News on Sunday that they’ve prepped more than 50 beats for Weezy that are just waiting for his blessing.

“In October, we shut the studio down and said, ‘This is “Wayne Welcome Home” month and we gon’ get beats every day for Wayne,’ ” Cool explained. “So he’s got a major catalog waiting for him.”
