I recommend you try it at home first with a metronome, until you get used to it.
By the way, I've recently done a lot of transcribing of lyrics, by listening to CD's made from old 78-rpm records. I've noticed it's very common for the tempo to gradually speed up during a song. You don't notice it when you simply listen to the song from beginning to end, but if you then immediately start over at the beginning, it's obvious that the beginning is slower. Obviously, these recordings were made before click tracks were invented.
This causes me to expect that when people play music the ordinary way, without a click track or metronome, they tend to unconsciously speed up during the course of a tune. There's nothing wrong with that in "real life," but I don't know what the consequences would be in a recording studio. Would it make electronic "fixes" harder to apply? And does an accelerating tempo sound more natural, or more dramatic? Can a click track be programmed to accelerate? These might be good questions to ask your recording engineer.
