Well, my band has been practcing for a few weeks now. Besides the occasional guitar ego, it's been great. The core group has contained drummer, me, guitarist A, and guitarist B, now we usually have a third guitarist playing with us, 3 or 4 guys around here who like it play. Last week we had a bad practice which ended in me, the drummer and guitarist A playing songs, we thought we sounded great and all agreed we had a good "connection". Everything was all good until today, they brought another bassist to practice. I played 3 or 4 songs, and left. I listened to the sit in guy, and i'm not too worried, he has some creative fills, but he is the opposite of me. He worries so much about fills, and flash that he usually messes up the timing, or it just sounds to busy. Me, well I serve the song, and will throw in a fill here or there when a song needs to be spiced up. I'm a young guy at 17, and wonder if I should compete for a spot in the band, or I could just look around the chicago metal scene for another one. This guy might just be a one-time jam session, but I'm not sure, what to do?
