Casey is on stool chat. His beard seems even a smidge shorter this week. He looks younger. Okay, he is singing the song "Nature Boy," written by Eden Ahbez and featured in the 1948 movie The Boy With Green Hair. People, wikipedia that movie, it is a morality tale with the message that war is dangerous for children (and gives them green hair). Nat King Cole sang the song, and then later David Bowie sang it, and it was also in the movie Moulin Rouge. What does it say about Casey's cultural references when he says it's from The Boy With Green Hair, not from Moulin Rouge? It says awesome things, that's what (assuming he had the choice). Jimmy Iovine wants Casey to sing Phil Collins' "In the Air Tonight," a song that I really like. But Casey doesn't want to lose himself, and he ignores Jimmy's advice. He sings with the upright bass again, along with a piano and percussion. This song has a mysterious, jazzy vibe, and Casey handles it well, although he didn't need to grunt and growl those couple times. He does a bass solo with some scatting that is wicked cool, and then shows great, non-growly, vocal range at the end. The judges give him a standing ovation. Jennifer Lopez talks about the variety of genres represented this season, and that you don't have to be a pop star, you can do a jazz album like Norah Jones. Randy also likes the artists on the season, and says that Casey is educating the people while embracing who he is. He shouts that the world cannot live by pop stars alone. I think maybe he's a little tired of Katy Perry? Steven Tyler says that his mama sang that song to him when he was a baby. That makes me want to learn it and sing it to my kids. (My current lullaby is "Soft Kitty," that couplet that Sheldon and Penny sing on the tv show The Big Bang Theory. When my 2-year-old sings it to his stuffed lion, it is adorable.) So to sum up: artistry, variety, jazz, yes. I much prefer this Casey to the angry screaming Casey of yore.
