If Dierks Bentley’s going to New York City next month, I may just have to go there, too. I mean, it’s only four days, right? And now with this four-pack of tickets for just $116 , anyone can see him perform his country and bluegrass music at each of those shows in cool clubs across the city. That comes out to just $29 a night. Granted, you’ll have to pay for cabs to get you around the city — from the legendary Bowery Ballroom on the Lower East Side to the swanky City Winery in Manhattan, then the cabaret-style Joe’s Pub in East Village and then the intimate Southpaw in Brooklyn. But if there’s a better excuse to go to New York from Oct. 18-21, I haven’t heard it.
