Addition of releases from "Early Version" of Band

Hi, I've been adding a bunch of releases to Coheed and Cambria's page recently, and I had a question regarding adding music from the band's previous incarnation. Prior to becoming "Coheed and Cambria", the band was called "Shabutie", and had four self-released EPs. I was wondering what the rules were for adding music from a band's previous incarnation. I swear I've seen this before on another band page but can't recall which one. Shabutie's line-up consisted of Claudio Sanchez, Michael Todd, and Nate Kelley (who was not a member of Coheed), as well as Travis Stever and Josh Eppard to a lesser extent. Two of the previously mentioned EPs contained rough mixes and demos for Coheed's first album "The Second Stage Turbine Blade". Would adding these EPs under Coheed's page be permitted? Sorry if there's already a topic for questions like this, I couldn't find it if there is.

Thank you!
