Weeknot || Slipknot x Weezer - Song Mashup || Island in the Sun & Duality 

Thanks! It’s not an extremely complex process. I look for 2 songs in the same key or their relative minor, then use a vocal remover AI or find instrumental & vocal tracks online. I then slow down/speed up tracks so they are of a similar tempo and then the vocal track can just be layered on top of the instrumental and edited to fit the song.

I felt that with Head Like a Hole / Island in the Sun, but this is really great
