The interview hasn’t started yet, but Moe Pope is already in a talkative mood. It’s a Monday night at the retail location for online record store Undergroundhiphop.com (UGHH) on Huntington Avenue, and as he unpacks equipment from a suitcase, he’s offering some advice to Casso, a 20-year-old aspiring rapper who makes a scene-stealing cameo on “Pressure,” a cut from Pope’s second full-length collaboration with producer Rain, titled “Let the Right Ones In,” which arrives in stores on Jan. 22.

“The great thing about life is that there is no ‘best,’ ” says Pope, who celebrates the album’s release on Jan. 25 at Brighton Music Hall alongside guests Ceschi, John Robinson, and others. “On Friday, people may want Moe Pope. On Saturday, they may want Ghostface. On Sunday, they may want to hear some Joni Mitchell. There’s an audience there, you just got to find it.”
