So here's my story: When I joined my current band (original band, previously signed to a now defunct indie national label, currently working on a second national release without a label) I was a guitarist, and converted to bass to take the spot. Our drummer is also a seasoned bassist, and had been tracking bass on recordings on the last two attempts to record new material before I joined the band. He replaced the original drummer after the last 3 song demo was released, so he never actually played bass on anything that has been released to the public... the band had not been happy with the recording quality from two previous studio sessions, and was planning on going into a new studio shortly after I joined. (I joined in April of 2012.) When I was offered the position, it was said that our drummer would be recording the bass in the studio, since I was new to the instrument and he could track cleaner and faster. I accepted that, as I was at the time unsure that I could pull off studio quality tracks at that point, seeing how I was still unfamiliar with the 5 songs they were planning to record and the session was only a month away. Fast forward a year later, the original plan to record 5 songs had changed as the session kept getting pushed back, moved to another studio, and then we got an investor who was willing to fund an entire album. Over the course of the year, I had upgraded my equipment, become far more comfortable with my instrument and role in the band, and I had written the bass parts for over half of the material to be recorded. Going in to the recording sessions, I was led to believe by our manager/producer that I would be tracking my own parts... but that changed come time for bass to start. It was said that the drummer would do it, to save time and money. We had blocked the studio out for the month, but we were still paying the engineer $30 per hour. After countless discussions and arguments, I was finally given my "chance to prove myself"... I was given one 3 hour session in which to track one song, and if the tracks were good they would be used. If they weren't usable, I would be responsible for the $90 worth of the engineer's time out of pocket. I agreed, and the first hour and 45 minutes of my 3 hours was spent on dialing in a good recording tone between direct, a sans-amp distorted fuzz tone, and a guitar amp through a cabinet for a gritty tone... the three of which would be blended together as needed for each song. I then proceeded for an hour and fifteen minutes to get roughly half of the song done, but was not able to complete the whole song. So basically, I paid $90 out of pocket to set up the bass tone for the rest of the tracking. Now, our lead guitarist tracks all of the guitar parts in the studio, again to save time as he is a much faster tracker than our rhythm guitarist. However, he tries to track exactly what the other guitarist plays, and checks with him if he is unsure of exactly how a part goes. Our drummer however, completely disregarded any parts I had written and proceeded to take his time rewriting all of my parts on the spot in the studio, often joking about how he didn't know the songs, had no idea what the arrangements were, what the guitars were doing, and so on... End result is that now I am tasked with the decision to either relearn all of the parts he has written, which are often far to busy and/or technical in my opinion for the songs, or to disregard what is on the album and play them as I wrote them, then having to explain why I don't play what's on the record. It is also my understanding that he will be credited with tracking in the album liner notes, which I will also have to explain somehow. It is a horrible position to be in, as I am finally in a band I have respected and envied since they first got together in 2005... at 34 years old with two kids, this is my "one last shot" at being in a national, touring, respected band playing original music for a living. But this recording has left a horrible taste in my mouth, so much that I am losing sleep at night over it. Should I take my lumps and roll with it so that I can "live the dream" moving forward, or should I tell them to shove it and try to find another bassist willing to take this crap treatment? For what it's worth, the singer is 100% on my side, and has said that he will fight as hard as possible to ensure that I am the only one who touches a bass in the studio on any future recordings... he is beyond pissed off at the drummer for the way in which he has disrespected me and my musicial ability. so it's not like they are all being dicks, and I do believe that the guitarists are only looking out for what they see as the best interest of the record. That I can understand, even if I don't agree... I personally think that it is the "flaws" in the rhythm guitarist's playing and in my own that help define the live sound of the band, and having two guys track all the music in the studio strips the life out of the songs and makes them sound sterile... but what do I know, I was only a huge fan for 7 years before stepping in as a member. How would you guys handle this situation, under my circumstances?
