Because he’s written so many great tunes for other performers, some people might get the wrong idea about Marshall Crenshaw. He’s also a fine singer. No matter how many celebrity vocalists have tackled his stuff, nobody puts more into a Marshall Crenshaw song than the man himself.

Naturally, the voice sounds a little more lived-in almost 30 years later, but the songs are every bit as finely crafted. Crenshaw is guest editing magnetmagazine.com all week. Read our Q&A with him.
