The best film scores walk a delicate line: They help propel the story, guide an audience's emotions and are also often a distinct character, with a role and voice as important as any actor's — but they also have to do all that without getting in the way, or drawing too much attention.

For this week's show, Bob Boilen and I throw open the studio door to welcome a parade of guests from the NPR Music team, each sharing their favorite April releases. This includes Jake Witz, one of our fabulous Spring interns, who has some relatively restrained music from U.K. grime artist Mr. Mitch.
