Depends how limiting they are. I'd re-record, so possibly that's the best (and complete) on, so you can just put the whole thing together like nothing happened.If you don't the new recording, include the original/chopped one. I'd make it sound nicer and fade out the end though. I'd include a note or something explaining what happened, although it maybe be better to just say the recording and backup recording got chopped. It still could make you look bad, esp. if you mention that you're the one who controlled making the recording (if that's true). So you say, "The recording and backup recording got chopped." They wonder, "Who was in charge of the recording?" but never get an answer. It doesn't answer the question of, "Why is he submitting an incomplete recording then?" though.If there was a power outage that affected both recordings, I'd mention that. If you've got enough of a recording, it probably really won't matter, depending on how much got chopped. The people listening are probably just going to note (yuck yuck) the piece and how well you play about ten seconds of it.So what I'd do...Re-record. Include/swap that if you like it better. Don't mention it, or just stick a very short note, "Original recording got cut off at the end due to a power outage, so this is a re-recording."If that doesn't work, maybe an older, complete recording with a note about that.Depending on how well you like that older recording, just send it off incomplete.If they're bring in you to play live later, the recording probably won't matter so much.I'd keep any extra notes about the chopped recording short for them. Otherwise, they're spending time on that instead of your playing.
UpdateCan’t reserve the hall till Saturday and apps are due friday
with stakes this high, you might call some recording studios off campus/private ones, see what kind of a deal you can get?
