Im looking for a copy of Hero of War by Rise Against but without words. Instrumental, karaoke, whatever you want to call it

Id do it myself but im currently without good recording gear for acoustic guitars

Im looking because i recently did a vocal cover of the song (here) but my voice is an octave lower than Tims and while it creates a kind of cool effect in my opinion it also detracts from the ability to key in on my voice (how selfish can i get? )
You can google ways to make it yourself. I know there are techniques to make karaoke with just Audacity. Or just simply google karaoke software. Otherwise, I don't know what to tell you haha
