About 12,000 Beastie Boys buddies gave the hardcore/hip-hop trio a hearty welcome-back party at the E Center Tuesday night.

The sold-out audience of mixed ages rammed, surfed and moshed themselves into a fury as the New York-based group thrashed and bumped through the night.The energy could have been attributed to the fact that the group hadn't done a full-fledged tour since 1995 (the group's core fan base in Utah has since outgrown the shaky walls of Saltair). Another reason could have been the fact that the Boys' new album, "Hello Nasty," debuted and is currently nestled in the No. 1 slot of Billboard's Top 200 album chart. Then again, maybe the excitement could have been because of the sonic blast and rush of having the Beasties back in business.

At any rate, the guys treated the audience to a sensory overloaded concert in the round.

Talk about energy. Once the three white boys from Brooklyn leaped on stage, the intensity didn't stop.

Dressed in blue lab coats, the Beastie Boys - Adam Yauch ("MCA"), Mike Diamond ("Mike D") and Adam Horovitz ("King Adrock") - shouted lyric after lyric as the band's current DJ, Mixmaster Mike, kept time with his turntable scratches.

The trio was joined on occasion by a backup band that literally added a giant splash of velocity to the mixes. But for the most part, the Mixmaster hand-swiped and created the illustrious soundscapes on which the Beasties rapped.

Among the dynamic binges of the evening, the Beasties played "Sure Shot," "Super Disco Breakin' " and "Time to Get Ill."

The heat, the sweat and the bodies flew. Not only were the thousands bumping and grinding, but some overzealous fans moshed and surfed the crowd in the numerous spiraling pits on the floor.

While mosh pits have become a staple at venues such as Saltair and private clubs, having them at the E Center did bring to mind the AC/DC tragedy at the Salt Palace in 1991 where three fans were crushed to death.

But luckily, West Valley police reported no life-threatening injuries at or near the Beastie Boys concert, even though a stream of fans rushed the floor when the lights dimmed.

Other bursts of adrenaline came in the form of songs such as "Song for the Man," "Intergalactic" and "Heart Attack Man."

The audience went ballistic during the night's capper, "Sabotage."

Opening the night was former Beastie Boys keyboardist Money Mark. His blend of pop and rock did have some of the audience going, but, for the most part, the applause was polite.

However, when second opening act Tribe Called Quest strutted and posed on stage, the audience gave its attention. The group got the audience worked up by plugging the Beastie Boys at every opportunity.

By the time the Beasties got on stage, the audience was primed and ready.
