R&B artist Lyfe Jennings has set an Aug. 15 release date for his sophomore album, "The Phoenix." As previously reported, the Columbia set includes a new version of slain rapper Tupac Shakur's anthem "Keep Ya Head Up" and will be led by the single "S.E.X.," which has just been delivered to U.S. radio outlets.

"I've wanted to write this song for a long time," Jennings previously told Billboard.com of the track. "[It's about girls] being confused by all the sudden attention when they start developing physically but not mentally."

Other tracks set to appear on "The Phoenix" are "Still Here," which features Three 6 Mafia and Project Pat, "Slow Down," which features G-Unit's Young Buck, the string-enhanced ballad "Stingy" and "Biggie Nigga," a tribute to late rapper Notorious B.I.G.

"The Phoenix" is the follow-up to 2004's "Lyfe 268-192," which has sold 975,000 copies in the United States, according to Nielsen SoundScan.
