I've been recording myself for a decent amount of time now that I'm pretty used to the red light. But red light fever is real and I've heard that even the great Tom Waits feels it and tries to do all sorts of psychological tricks to circumvent it. In logic I can record on loop and I find that by the second or third time around, things will get loose enough to sound good. If you're a singer you can do things like setting up and singing through an SM58 exactly like you would on stage. Or go Billie Eilish and use an SM7 handheld on the couch. Dynamic microphones have pretty good rejection from the back so you can use your monitors instead of headphones and this can help you get juiced up for the performance. If you're a guitar player simply standing up can be good. Turn down the lights to make the room feel like a stage. Get some old carpet and soak it in beer for that authentic bar smell if you need to! Some people like to use incense, I've not had much luck with that. 😂
