When you interview someone as well known as Brandi Carlile, you sometimes get a pleasant guy named Sean or Chris who calls to let you know that the phone interview has been canceled. Someone named Shannon reschedules. When everything is sorted out, Sean or Chris will call to connect you to Carlile, letting you know that in 15 minutes he will chime in on the line to give you a five-minute warning. Carlile, 30, is touring behind her fourth studio album, "Bear Creek," which came out last month, peaking at No. 10 on the Billboard 200 and No. 3 and No. 1 in rock and folk respectively.
