Jeff Beck found a kindred spirit in Johnny Depp when the two met in 2016. They bonded quickly over cars and guitars and spent most of their time together trying to make each other laugh. At the same time, Beck's appreciation grew for Depp's serious songwriting skills and his ear for music. That talent and their chemistry convinced Beck they should make an album together.

Depp agreed and they started in 2019. Over the next three years, they recorded a mix of Depp originals along with a wide range of covers that touches on everything from Celtic and Motown, to the Beach Boys and Killing Joke. In 2020, during the pandemic, they previewed their collaboration with their well-timed cover of John Lennon's "Isolation."

Beck explains the album title: "When Johnny and I started playing together, it really ignited our youthful spirit and creativity. We would joke about how we felt 18 again, so that just became the album title too."
