I've been running into an issue with a guitar player in a four piece band I play in. Two guitars, drums, and me on bass. Three of us have been playing together for a long time, but we've been playing with a new guitar player for the last few months. He's great musically. We spend most of our time writing originals, and he's very creative, often writing parts that just gel so well with what the rest of us want to do. We like a lot of the same music and mostly want to write the same kinds of songs. The problem is that he just hears things totally differently than the rest of us. We'll record or play a really good take of one of our songs, and three of us will be jazzed about how great is sounded, and he'll say it wasn't very good. We'll play a sort of mediocre, sloppy, half-hearted version of a song and he'll think it's the best we've done on it. We'll play a song that with a lot of syncopated minor pentatonic riff-heavy stuff in in, and he'll say it sounds too happy. We'll play something with a danceable groove or repeating hook, he'll sound it sounds to happy. Then we play our most major-keyed upbeat, poppy song, and it's his favorite! He interprets syncopation and dual-harmony lines as corny and trite, but interprets a 1-4-5 power chord riff as edgy and experimental. I love playing music with the guy, but it's just a bummer sometimes when his ears hear everything so different from the rest of us. Have any of you ever played with someone like this, and what did you end up doing about it?
