Four years ago, Eels founder Mark Oliver Everett decided to take a break from music. He went on what he calls a project of self-improvement, during which he got married, got divorced and, at the age of 54, had a son. He also spent time reckoning with the losses he’d experienced earlier in life, including his sister’s suicide, his mother’s death from cancer and his father’s fatal heart attack. Now he’s back, with a new album, ‘The Deconstruction,’ a reflection on both the pain and joy of life. Also, John Powers marks the 50th anniversary of the Stanley Kubrick film, ‘2001: A Space Odyssey.’ And Dan Stevens, who played Matthew Crawley on ‘Downton Abbey,’ now stars in ‘Legion,’ an FX drama that’s a spin-off of the Marvel Comics ‘X-Men’ series. Stevens talks about Crawley’s untimely death, and wearing a motion capture suit in the live action ‘Beauty and the Beast.‘
