Now that the North Carolina hip-hop trio Little Brother has disbanded, fans of the group’s members--rappers Phonte and Big Pooh and producer 9th Wonder—must be content with their respective solo projects. Since 2004, Foreign Exchange has been Phonte’s side gig, with Dutch producer Nicolay. They’ve just released their third album, last year’s Authenticity, and what started as fun experiment in long-distance musical collaboration could soon be what both men are best known for.
