What is the difference in rate between doing a demo deal, or doing an album?
The rates, equipment, and availability are all the same, regardless of whether the recording is for a demo or an album. The price difference that can exist between the two though is related to the amount of time/care taken with the recording. Depending on how far you wish to take it, fine tuning your instruments sounds, and making sure you got the right take is where extra time (and therefor cost) will be added. Also, for bigger projects it’s recommended to mix on a seperate day, so everyone has fresh ears and has a clearer concept of what needs to be acheived with the recording.
