Jonathan Wisniewski and mastering engineer Mike Kalajian nerd out on whisky and IPA's for the first 20 minutes of the podcast. Then they define what mastering is, the misconceptions surrounding it, the creative aspect of it, working on a master and thinking "yeh", what should artist's keep in mind with their arrangements, working through revisions, the loudness war, and much more!
