The back story: My band is in the studio recording throughout February and into March. All of us are roommates and our 5th roommate is a keyboardist/trumpet player that a few of us have played in bands with in the past. We asked him in December if he'd be willing to lay down some keys and one trumpet track in the studio and agreed upon fair pay for the session. We completed one session in which he wasn't needed, mostly getting drums and rhythm section down, and are going in for our second session on Wednesday. He's on board for the session but he doesn't drive, so will be getting a ride to the studio with us at 9AM, then getting a ride to work from a friend who lives a block or two from the studio around 1PM, at which time we'll stick around until 5PM to do some finishing and some post-production work. He has recently (Since terms were agreed upon) met a girl and has been spending the majority of his time with her. He's missed the initial and re-scheduled pre-recording rehearsal days that we scheduled, though I'm certain he has been practicing as he works as a music teacher. He has recordings of the tracks and has played with us before, so I'm sure he will be able to pull off the session, but because of missing out on rehearsal he's been somewhat misunderstanding of what we require of him. He was told that he will need to have his keyboard and trumpet available and that there will be a rhodes and a hammond there for certain songs. One of the songs will require a piano tone on it as it's got a country/honky-tonk vibe that e-piano just won't do. His keyboard is at his main band's guitarist's house 30 miles away, and the guitarist is refusing to take calls from anyone in my band. Our options are to get our hands on his keyboard at a later time and hope that he can make time to come in for another session, rent a keyboard for the day and lose some of our studio time to go pick it up, or can him and push back the release date so we can find time to vet both a keyboard and trumpet player. He's a good guy and I can understand wanting to spend time with a new flame but it's a bit frustrating. It's already decided that whatever the result is it will affect his reimbursement pursuant to our terms of agreement, since we were hiring him and his equipment, not just his abilities.
