AIRSHOW ENGINEERS HAVE MASTERED over 90 GRAMMY-nominated projects. The unique contribution of the mastering engineer is recognized in the Historical Recording category. David Glasser and Charlie Pilzer were awarded the GRAMMY for their work on the culturally-significant reissue, The Anthology of American Folk Music, (Smithsonian Folkways), a 6-disc box set reissue of the Harry Smith collection. Its original release was a major influence on the folk music resurgence of the '60s. 1997's Best Historical Recording honors were shared with the project's producers, Jeff Place, Pete Reiniger, and Amy Horowitz.

David Glasser and Matt Sandoski earned the 2002 GRAMMY award for their work on the critically acclaimed Screamin' and Hollerin' the Blues: the Worlds of Charley Patton (Revenant Records). The award for the 7-disc set was shared with Christopher King, the collecting engineer, and the project's producer, Dean Blackwood. We share the honors with the late John Fahey, Revenant's founder. John passed away during the production of the project, which was the culmination of his life-long study of Patton's blues influence.

In 2004 David Glasser and Matt Sandoski were nominated for their audio restoration and mastering work on the epic box set Goodbye Babylon, a 6-disc collection of gospel recordings dating from the 1920s through 1950s. Also nominated was the project's producer, Lance Ledbetter, who released the box on his new Dust-to-Digital record label. The nomination is for the Best Historical Album. David Henry assisted Dave and Matt in their work. The project also garnered a nomination for package designer Susan Archie.
