The stage version of Nel Gaiman’s ‘Coraline’ is previewing in New York this week with music by Stephin Merritt of The Magnetic Fields. The perennially blissful Merritt is busting at the seams with his usual brand of enthusiasm, telling Spinner dryly, “I don’t get excited.” Ah, well, ok. He continues: “I’m not that type of person. I’m not having that feeling yet and that feeling will probably be something more like terror. Probably there will be something going horribly wrong at the last moment, as usually there is, and I’ll have to figure out how to solve it while worrying that I won’t succeed.” Inspirational words for aspiring composers.
