Having cut his teeth within the small but tight-knit Green Bay punk scene of the early 2000's, Milwaukee-area producer/engineer Justin Perkins gives tips on mastering records both digitally and for vinyl and discusses temporarily joining Screeching Weasel, being in charge of documenting the final Replacements reunion show in 2015, and how trying to change an album's audio mix after the mastering process is like attempting to cook an already-burnt pizza. Visit mysteryroommastering.com for more info on Justin's studio work, and check out BashAndPop.bandcamp.com to hear his recent musical project, backing up the Replacements' Tommy Stinson!
