We're proud to have interviews with some of the engineer/producers who helped define the new sounds of rock over the last 30 years. Ken Hamann cut his teeth on classic 60s bands like The Outsiders before working with Pere Ubu. Spot recorded classic post-punk records for The Minutemen and Hüsker Dü in the 80s. Jack Endino helped define the "Seattle Sound" with his recordings of Mudhoney, Nirvana and more. Other people, like Geoff Turner at WGNS and J. Robbins helped define the vibrant DC scene, the members of Calexico have been recording atmosphere laden "desert rock," and "Roscoe" has been a leading producer in the "alt-country" world. There's room for a lot of creative, fun recording out there and I think this issue's articles illustrate that well.
