Drawn from their Annenberg Italian-style “festive meal” by loud music coming from the usually tranquil home of math review sessions, others flocked spontaneously to Loker during the hour-long set on Wednesday.

Frontman Tom P. Lowe ‘05 sang at first to an almost empty floor on Wednesday. But the band played with an energy and charisma disproportionate to the crowd, unleashing catchy, beat-driven rock and jazz to an initially timid group of high schoolers.

The crowd eventually responded favorably—ultimately, devotedly—to the 27-year old frontman.

“They’re so enthusiastic,” said rising high-school senior Chelsea A. Molly, 17. “The singer was totally into it the whole time.”

The crowd was transfixed by Lowe’s command, rising when asked, dancing when demanded, and shouting for an encore when prompted.

“We don’t bite,” one of the Tigers said while asking the crowd to close in on the stage.

“Unless asked,” Lowe rejoined.

Gradually, the crowd moved from the back of the room and began dancing front-and-center as the band played its Boston anthem, “City on a Hill.”

Tommy and the Tigers started with show tunes and moved between up-tempo, bass-heavy rock and slower, more “grooving” tunes.

“We call it dance rock. We’ve sort of been described as George Michael-meets-Jamiroquai,” Pertz said. “It’s meant to get you up and dancing in the aisles.”

He said the band also met a warm reception Tuesday night.

While the set remained the same on the second night, reactions to the less-than-full audience were mixed.

Some appreciated getting within spitting distance of the former West End actor and boy-band star.

“I felt like a VIP,” said rising high-school senior Alejandro Rojas.

Others found their peers’ lethargy disconcerting.
