The Mane 5 celebrate a musical festival in Bridlewood for the season with multiple bands performing.
The Mane 5 are trying to stage a music festival during Bridlewood's beautiful Lumi-Bloom, a gorgeous bioluminescent nature event that only happens once a year. Throughout their quest they race to book Equestria's best and brightest artists, reunite old legends, and grapple with the unicorn legend of voice stealing Troggles.
