Halfgain was a high nu metal band they only released one album and after that they dipped (like almost every underground nu metal band) i guess when they grew up they were embarrassed of the band and so they removed of spotify and basically everything however there is still youtube videos out there of the band performing and music videos

After they graduated all of the members had different ideas of what they wanted to do and the lead singer is now in a different band called "DED"

Hopefully halfgains music will be recovered someday but I highly doubt it
