Jaill, with The Hold Steady. Showbox at the Market, 1426 First Ave., 628-3151. 8 p.m. $24. All ages. Although it’s fairly far along in the game, the perfect soundtrack for this summer may have just shown up. Straight from the shores of Milwaukee, Wisconsin, Jaill’s second full length (and first on local tastemaker Sub Pop), That’s How We Burn, plays like a perfect boat ride, with just enough jittery, choppy moments to balance out the smooth sailing. Full of reverb-laden major key jangle and cooing, sunny harmonies, Jaill is a surprisingly upbeat, catchy affair at first listen; raw in all the right places, with just enough sugar sprinkled over it to keep listeners bouncing off the walls. However, dig into the meat of the lyrics, and Jaill has just the right amount of salty world-weariness to make the perfect bitter/sweet combination. GREGORY FRANKLINFran Healy. Triple Door, 216 Union St., 838-4333. 8 p.m. $25. All ages. Why did Fran Healy, the lead singer of the acclaimed Scottish Britpop band Travis, make a solo record, this fall’s forthcoming Wreckorder, without his longtime bandmates? “I hate them,” Healy told me on a recent phone call. “I hate all of my band. They’re all wankers.” In all seriousness, Wreckorder came about during a much-needed rest period for Travis last year – Healy says he wrote the songs to “invigorate my brain and inspire me” The result? A gorgeously sweeping collection of grand and richly arranged pop songs featuring Healy’s tender-sweet vocals, as well as a heart-aching duet with Neko Case and, on another track, a musician named Sir Paul McCartney on the bass.
