The first thing to know about pop rock group Radical Something is that these guys know how to use their music to throw a party.

The California trio is comprised of singer/guitarist Loggy (or commonly known as Alex Lagemann), singer Josh Cocktail (Josh Hallbauer) and multi-instrumentalist/DJ Big Red (Michael Constanzo) and the three blend eloquently in a harmony of upbeat, good vibin’ pop. Radical Something is entering the tail end of its national tour, and the trio sounded glad to be back in Eugene performing at the EMU amphitheater. “We drove 10,000 miles [in this current tour],” said Loggy on stage. “Y’all get to share the last leg of the tour with us!”

This stop in Eugene was in support of Radical Something’s new album “Ride it Out.” The album cover features the three musicians chilling by a blue backdrop wall, but their heads have been digitally removed. Josh Cocktail sees the image as a good symbol to describe the band.

“Let the music speak for itself,” he said. “We feel like we brand ourselves and show our faces with everything, but when it comes to the music it’s the one thing that the music should just speak for itself.”

The group’s influences are all over the place with elements of hip-hop, reggae and rock. Each member brings his own flavor to the tightly woven mix of catchy tunes. Josh Cocktail supplies the backing vocal hooks, while Big Red keeps the vibe grooving with his slick bass line and Loggy raps it all together.

But Radical Something’s performance was more than just the three dudes rallying up the crowd to dance and have fun. The two hour concert was a variety show filled with music, comedy and prizes.

Kicking off the event was DJ Big Red who threw down some DJ mixing and set up a casual lounge vibe throughout the amphitheater.

After his set, Radical Something took the stage, and what began as a feeble gathering transformed into a full-on party with fans singing and clapping along to every song preformed. Radical Something has crafted its shows in such a way that audience interaction is guaranteed and in constant flux. This night, the band entered the crowd and handed out high-fives. DJ Big Red even let a fan hold his mic as he rapped along.

The crowd was highly involved and appeared to love every moment of the show. In the front row, a young buck wearing a colorful bucket hat sang along to each lyric without missing a beat during Radical Something’s recent single, “Ride it Out.” He danced with his left arm in a sling and his right hand in the air, swaying with the music as Radical Something continued their party-funk pillage.

Midway through the performance, Loggy slid off his t-shirt revealing a bro tank and yelled, “Who wants to dance?” Simultaneously, Big Red threw on a pair of sunglasses (it was very dark outside but this act was warranted) and the trio inspired the whole crowd to bounce along to their next track, “Cheap Drink.”

Around this time, Radical Something completed a show ritual and took a photo with the entire audience. Fans huddled around the three performers, sweat and all, and raised their Oregon O’s high.

The group plays songs that would fit well for any college day rage when the sun is out and the keg is nowhere near tapped but, surprisingly enough, this isn’t the trio’s mission.

“…That’s the funny thing is, we don’t look at ourselves at all catering to college. We don’t talk about college parties, we don’t talk about beer pongs and red cups, we have nothing to do with Frats and Sororities in our lyrics … Two of our biggest markets are not college,” said Loggy about their fans. “They’re high school and people that are within the 28 [years old] to 72 [years old] range.”

“It’s definitely 16-28 though,” continues Loggy. “That’s the core fan base and stuff. And they grow with us. That’s the good thing about high school kids: They go to college and spread the music. But we feel like our music…”

“Timeless,” Josh Cocktail quickly inserts.

Radical Something played on until the trio ended the show with a collective, “1-2-3 peace” with the audience, and music shifted from reggae to pop and even dabbled into some heavier dub step. The group’s energy was dancing with the good vibes. It seemed as if no matter the size of the crowd, be it 10 people or a 10,000, Radical Something will get everyone to groove with them.
