The certified “LO-head” 88-Keys supplies a new remix to Common’s Testify single, which was featured on his 2005 album, Be. Below are some more details on how things all came about from 88 Keys.
I hit up Kanye & asked him if he had the a cappella files for this (which wasn’t out at the time). He gave me the files without hesitation. I turned over this remix rather fast but never finished it because I couldn’t come up with a hook for it. I played it for Kanye & he liked this a lot. So much, in fact, that he was going to reach out to Brandy to lay a hook down on this. Unfortunately, for me, Common didn’t feel this half as much as ‘ye did.
