Even if we’re working together in a capacity where I’m not producing you, just being your recording engineer, I still recommend you use the info above to demo the material on your own in advance of our session. That preparation will yield better results once you’re on the studio mic doing final takes. Many musicians relate to the experience of having a certain level of competence with a piece of music only for it to feel like their capacity to perform it drops 25% on stage or in the studio when the red light goes on. You may even feel totally confident with it on stage only to find that the more forgiving live environment was hiding your rough edges once you’re in the studio. Demo what you’re going to record to get a more accurate sense of where you’re at with it so you can adjust before hitting the studio. Having my own studio, I have free unlimited studio time and I still don’t allow myself to record something until I’ve sung it to my phone first. I hope it goes without saying that practicing your vocals and instruments prior to a recording session makes a smoother experience for all involved.
