Wiz Khalifa, Curren$y Give Live In Concert A Smoking 4/20 Release Day

The How Fly rappers will drop their delayed collaboration Saturday.

Rap's Cheech and Chong are ready for a reunion. Wiz Khalifa and Curren$y hopped online on Wednesday and announced that their long-awaited, collaborative project Live in Concert will be released for free online on April 20, the unofficial stoner holiday.

"We've been talking about Live in Concert for a year now," Curren$y said while on a live YouTube stream. The tape that was originally supposed to drop on August 9, 2012, but has been delayed due to sample clearance issues. "There were some hurdles, a little red tape we had to cut through in the music business that happens to keep us from getting sued."

Staying true to form, the duo, who released their first collabo tape How Fly in 2009, smoked weed throughout the 16-minute broadcast and even treated fans to a tag-team rendition of Max B's "Porno Music."

After their expletive-filled rap, Spitta joked about losing sponsorship dollars, an obvious poke at the Rick Ross losing his Reebok deal. "I'm probably gonna lose my Sea World endorsement. I just signed a $20 million deal with them," he said in jest.

Last July, Curren$y visited "RapFix Live" and told show host Sway Calloway that the seven-song project was completed over the course of two days and they got as creative as they wanted to be.

"When me and [Wiz] work, there is never a structure to it," he said. "So, some stuff might be 11 minutes, some songs might be 30 seconds. But in that 30 seconds, you would've got like two hours' worth of game."
