Its new album, “Culture,” debuted at No. 1 on Billboard with the single biggest album-streaming week by any indie artist in SoundScan history (116 million streams). That made it the most-streamed debut ever, even ahead of Beyoncé and Justin Bieber. See what all the fuss is about during this official iPower birthday bash, with Cam Cooper and Pam Nicole as hosts, going down Friday, March 24, at Altria Theater.
