Tracking in a non-studio environment can engender a great vibe that can have a very positive effect on musician / artist performance. One disadvantage is the amount of setup time involved in working in a space without a studio’s infrastructure. There’s a lot of equipment to put in place if you’re doing a full-blown multi-track pop production. Mic lines, monitoring, a headphone system, outboard gear, etc. Of course, there are also potential issues with environmental noise and sub-par acoustics.
Still, the results can be spectacular. Here’s a recording I did in the artist’s living room. I was set up in the same room, just behind the line of cameras, trying to get the best sounds I could in a compromised monitoring environment. In these situations, you rely on your experience of best practices to guide your engineering decisions. We could have made this in a recording studio, but I don’t think it would have been nearly as cool.
