In a release, Burger Records stated:
"Burger Records loves tapes! We've built our foundation on the forgotten format and have been preaching the merits of warm analog cassette culture for years. We're honored to be ambassadors of Cassette Store Day 2014 in the good ol USA! We plan to bring some of our favorite labels to the table and invite everyone to the party and partake in the fun phenomena of releasing top shelf music on cassette tapes in pop culture today!"
