Exactly a year after the release of The Harley Rager Collection, Harley Rager has described it as a 'door-opener' on his side, and to show gratitude, he released the Anniversary Edition. After constant experimentation with different sounds, he gives us another 10-track mixtape where he raised the bar higher than last year, from the smooth piano intro from "A Word From our Sponsor" to the rock guitars in "Killer Queen". Rager also gives a taste of Amapiano on the second chapter of the mixtape months after "The Harley Rager Collecton II" had been released. Rager mentioned in a podcast that the release of this mixtape marks the end of the "Sick Pleasure MMXXI Saga" and that the year had been "the greatest joyride in music" he had ever taken.
