The septet kicked off their 2018 Festa celebration with a new version of the 2017 single.
BTS is celebrating their fifth anniversary with the release of an alternate, rock version of last year’s sentimental hit “Spring Day,” the group’s first song to break into the Bubbling Under Hot 100 chart.
The rock version of the song was performed by BTS’ band Ghost, according to the Soundcloud credits. It was originally unveiled at South Korean channel KBS' 2017 year-end music festival on Dec. 29. The song was released in February of last year.
