Well, I typically make remixes using the a Capella vocal stem...like my "Like A Star" remix uploading soon. It depends upon what you want me to add: instruments to a vocal (my specialty) or just vocal mix/mastering to an instrumental.
Let's collaborate on a mix! Here's my idea... The tracks at indabamusic.com it's called "Time" by Conrad Clifton. You create your magic on the vocals and I want to put the vocals on a track that's Pantera meets Incubus!
