After the marvelous job Buck did for Lando, I sought him out to do a new cover of Ben E. King's 'Stand By Me' to go along with my now-completed fanfic It's Always Blind (I hear it's great and you should read it). There's actually an official cover out there in an episode, but it's short and not properly released, so it was more of a missed opportunity than something I could call on.
Buck's cover, on the other hand, came out amazing! Could not be happier with the result.
Speaking of which, I believe he's taking commissions right now. So you should go throw money at him, because he really does good work.
