N.E.R.D debut new music in Austin, Texas (AP)

AUSTIN, Texas - N.E.R.D.'s new single "Everybody Nose," which depicts a club-hopper's drug use, could be the theme song for out-of-control party girls on the celebrity circuit. But frontman Pharrell Williams says the song is not chastising people for their questionable habits.

"The message is just making an observation. It's not us condoning or glorifying it or talking about people who do it," the superproducer told The Associated Press on Friday. "We're just saying America, look at what's going on ... this is what it's like this is what this girl does."

"Everybody Nose" is the first new music from the eclectic trio in years. The group -- which includes Williams' Neptunes production partner Chad Hugo and friend Shay Hayley -- haven't released an album since 2004, and were debuting some of their new music at performances at the South by Southwest music festival. Williams said the group took so long because they were "waiting for the right moment."

"There's a lack thereof of energy, so we just wanted to be one of the bands that would re-install that energetic feeling," said Williams, who along with Hugo has produced for acts ranging from Beyonce to Jay-Z to Justin Timberlake.

"I think it sounds more aggressive, more focused on emotional buildup and just way hotter, it's way better -- its louder, and it's more texturized," said Hugo of their sound, which ranges from hip-hop to punk sounds.

N.E.R.D. -- which stands for "No One Ever Really Dies" is due to go out on the road with Kanye West, Rihanna and Lupe Fiasco in April. The group's album is due in June.
