City Councilor John Connolly’s bid to unseat Mayor Thomas M. Menino by tapping into new and young voters will get a boost tomorrow with a free show by red-hot Hub band Bad Rabbits, the Herald has learned.

Bad Rabbits — veterans of the Vans Warped Tour and heroes to legions of Hub hipsters — will play a free show at 6:30 p.m. tomorrow at the Omni Parker House as part of Connolly’s official mayoral campaign kickoff. Also expected to make an appearance is Dorchester rapper Akrobatik, another acclaimed Boston artist, who is a high school friend of Connolly’s.

Greg Selkoe, CEO of online retail giant Karmaloop and a vocal Menino critic, is slated to introduce Connolly.

“He wants to run a different campaign and wants to tap into the hundreds of thousands of people who vote in national elections and get them to finally participate in a mayoral election,” Selkoe told the Herald today. “I’m excited about it.”

Selkoe, who also founded the Future Boston Alliance, a nonprofit that supports upstart Hub businesses and artists, added: “I think John is a solid guy and I’m honored to speak.”

Menino, 70, has not yet said whether he’ll seek an unprecedented sixth term.
