Enjoy “Next,” Chris Bro’s show on The Peak? After all, “Next” gives listeners the chance to hear new music by not-all-over-the-radio artists like Bishop Allen, M. Ward, and The Decemberists. As it turns out, being a “Next” fan would be good for the world, too. The show’s Charity Concert Series, which takes place over-the-border at Rack ‘n’ Roll in Stamford, Connecticut, donates its proceeds to Big Brothers Big Sisters. For a five-dollar admission, hear new music from emerging artists like Kaiser Cartel, Matt O’Ree with The Bonesmen, and Nikki Shannon. Not only will you get cool heard-of-them-first cred, but you’ll get to help out a good cause.
