Musician Raj Ramayya has done a fusion style cover of Butter-Fly.
Titled, "Butter-Fly Dual World Version", Ramayya has re-imagined the song as a sort of dueling Jazz/Rock-style combo to celebrate the release of Digimon Adventure tri. part 4.
The atypical styling was apparently done to represent the various dualities of Digimon, most specifically the idea that they have relatively calm everyday lives of friends and families contrasting with their saving two worlds with their partners.
If you are an anime fan, you might not know his name but Raj has previously been involved with anime and games. Most notably he was a guest vocalist for Yoko Kanno and the Seatbelts for Ask DNA, the intro song for the Cowboy Bebop movie, along with writing the lyrics for the end theme, Cosmic Dare.
Butter-Fly Dual World Version can be found on various streaming/download services such as Spotify and Apple Music/iTunes.
Information about the release, along with a medium quality copy of it were sent to WtW unsolicited via Ramayya's label. I listened to it and liked it and thought some of you might also.
