You won’t be seeing Mark Knopfler in melodramatic newspaper headlines or on talent show panels. The much-travelled craftsman prefers to reside wherever the song takes him, from writing room to rehearsal space, recording studio to concert hall. He is, as tirelessly and inquisitively as ever, on the trail of some musical truth, just as he has been since the 45s of Ricky Nelson and Lonnie Donegan, or the playing of Hank Marvin and Duane Eddy, sent him down a path that led to 125 million record sales.
