Billie Joe Armstrong and Green Day make return at SXSW festival

Billie Joe Armstrong is back and rocking along with his band, Green Day, as they performed at the South by Southwest Festival Friday night. The concert took place at the Moody Theater in Austin.

According to Rolling Stone, the band's frontman is clean, sober, and ready to rock. And he did just that - people who attended the concert said he was full of energy and joy.

"This is not a f***ing party, this is not a first date, it's not a bar mitzvah – it's a celebration,” Armstrong yelled during a song.

The festival was the first time the band returned to the stage since the I Heart Radio festival in Las Vegas, after they had to cancel a list of shows due to Armstrong's drug and alcohol problems.

The band planned to return to the stage March 28 but decided to start a little early for 2,750 lucky fans, reports MTV. The band rocked on for a two-hour set.

There was also plenty of crowd surfing and fans participating onstage, just like at any other Green Day concert.

"Who wants to come up here?” asked Armstrong during "Know Your Enemy."

The set included many fan favorites from over the years like "Longview," "Boulevard of Broken Dreams," and "Basket Case." They also performed their new single, "X-Kid."

It seems that Armstrong is free of his troubles, and the band is ready to get back to rocking cities again.
