Shellac At Action Park is Shellac's first LP. Previously the band released "The Rude Gesture (a pictorial history)", "Uranus" and "The Bird Is The Most Popular Finger", all seven inch 45s. They are all still available.

The album was recorded electrically, and features no overdubs, no guest appearances and no tiny cymbals that go "pish". The LP format of Shellac At Action Park is an audiophile pressing, manufactured to classical standards. Mastering is all analog, direct-to-metal (DMM), and the records are virgin, dye-blackened vinyl, weighing 177 grams (the nice thick ones that don't bend).
