“Let’s get dirty!” Weezer’s Rivers Cuomo (vocals) continuously screamed to a sea of thousands at the U.S. Open in Huntington Beach on Saturday.

Perhaps due to the beach-party environment, Cuomo was extremely enthusiastic and never still on stage. With crazy antics such as hanging from a camera pole, walking into the stands and jumping on an onstage trampoline, the performance was nothing short of entertaining and unique.

Opening with their hit, “Hash Pipe,” the band had the crowd dancing and forming awkward and seemingly out-of-place mosh pits. Fitting for the song, the smell of weed began to disperse throughout the crowd, despite dozens of cops surrounding the beach.

Cuomo demanded a camera from a random videographer in the photo pit and began to film the crowd as he ran around the stage while performing the guitar-infused song.

Almost too fitting, as the band played “Troublemaker,” Cuomo made his way onto a stage-right platform and dangled from the pole of a swivel camera that hung above the audience. Suspended in the air above the huge crowd, which literally covered the entire beach, Cuomo proved that he was just as entertaining and daring as he was when the band formed in 1992.

During “Surf Wax America,” Cuomo ran across the barrier and let his fans grab him, almost as if to thank them for waiting in the hot sun all day. To entertain the audience even more, the band threw rolls of toilet paper into the crowd during the song.

As Weezer played “Can’t Stop Partying,” featuring Lil Wayne from their 2009 release, “Raditude,” the group was very in spirit with the song as they tossed giant beach balls into the audience.

Cordless mic in hand, Cuomo made his way into the stage-right bleachers and sang along with a fan during “Beverly Hills.”

The band played a cover of Lady Gaga’s “Poker Face.” In the spirit of Gaga, Cuomo emerged on stage in a blonde wig and began impersonating the pop star.

After a pause of a few minutes, the band came back on stage for an encore with their hits “(If You’re Wondering If I Want You To) I Want You To” and “Buddy Holly.”

As the band played most of their hits, the set was a flawless way to end this year’s U.S. Open free concert series.
