As Skrillex, Sonny Moore is a fairly astonishing thing – a musical superstar who has never released a proper album. This may suggest a cultural paradigm shift, or simply a DJ with little to say beyond the dance floor. His latest free EP leaves the question open. "The Reason" is an electro-house exercise with pitch-shift changes leading up to a mighty build-and-release, while "Scary Bolly Dub" is boilerplate bro-step wobble with a Bollywood infusion. Only the down-tempo title track finds compelling melodic and emotional turf, conjuring loss with some lonely keyboards, spacious percussion and a single repeated word. It's a song-let, like the entire EP, that's standing on the verge of getting it on.

“Help Me”

Joni Mitchell wrote and recorded this song for her album Court and Spark, but she had to switch from her regular band to make the song sound exactly the way she wanted. "I had attempted to play my music with rock & roll players," she told Rolling Stone. "They’d laugh, 'Awww, isn't that cute? She's trying to teach us how to play.'" Mitchell switched to a jazz band, Tom Scott’s L.A. Express, and scored the biggest hit of her career in the process.
