Jersey rock band Rainbow Fresh plays terrific driving music: tough, throbbing, hard-rocking, gas-pedal-down highway songs, built around propulsive six-string riffs. Frontman Rich Seiner, pictured, has a strong voice, a better guitar sound, and a library of classic rock favorites that he's inspired by. Led Zeppelin is the most obvious touchstone, but there's more than a little psychedelic Floyd and pop-smart Steve Miller Band in his delivery. On 'Dark Sun', the group's latest release, Seiner and his bandmates put those skills and influences to good use - they're inviting you to roll down the windows, hit the interstate, and sing along. This summer, Rainbow Fresh will be all over the Garden State: The band is appearing at the Triumph Brewery in Princeton next Friday, the Jackson Premium Outlets the next day; then they'll pack up their gear and play in Manville that same evening. (This rock outfit is indestructible.) Tonight, one of the hardest-working bands on the local circuit will be howling by the shores of Lake Hopatcong. Seiner brings the rock to Mount Arlington's oldest drinking establishments. Appearing at Pat's Tavern, 390 Howard Blvd., Mount Arlington, 9 p.m.; no cover; call (973) 288-1997.
