Tommy and the Tigers cut up the floor of Loker Commons during a free concert for Summer School students Wednesday evening. The high-school audience danced to strains of “City on a Hill,” the band’s Boston anthem.

Tommy and the Tigers’ rock music and risqué message hit a precollegiate audience Wednesday night, when the band serenaded a small crowd of high-school-aged Harvard Secondary School Program students in Loker Commons.

Wednesday’s night’s concert, attended by about 100 high-school students, was the second in a two-night stand for the band. The previous night, it played to an exclusively college-aged Summer School crowd.

The earlier concert drew approximately 50 people, “which was a great turnout for 7 o’clock on a school night,” said T. Josiah Pertz ’05, the band’s publicist.

said. “They were very enthusiastic, and some approached us about hearing some more of our music.”

The rock concert series, scheduled by Summer School Dean of Students Christopher S. Queen, was an unusual offering for Summer School students.

“We have quite a visiting-artists series every summer,” Queen said, mentioning theater, dance, and symphony performances arranged for the summer school students. “We usually don’t book rock bands because there’s so much going on in Boston.”

Queen also cited cost as an obstacle to booking rock acts.

“These types of acts are usually a lot more expensive,” he said.

Tommy and Tigers initiated contact with the College, according to Pertz.

“We had approached the summer school about performing in Loker because we were looking for a place to show off our music,” said Pertz, who is also guitarist for the four-member band.

The band requested to do one free concert, but Queen countered by asking for two concerts and offering to pay the band for the shows, which he described as an “early study break.”

The concerts come as College administrators attempt to make Loker a more student-friendly place. The College hosted a series of pub nights in the space this past academic year.

“I think last night was a lot of fun and I think the summer school students really enjoyed themselves,” said College Campus Life Fellow, or “fun czar,” Justin H. Haan ‘05. “I think it’s also a testament to making pub nights what they are and how ill-equipped the space down there is to serving that need.”

The fallout of the quickly planned concert was a paucity of publicity and attendance.

“I heard about it 10 minutes ago,” said rising high-school senior Billy A. Organek, 17.
