When I started out as a sound engineer in the early 80’s there were no drum loops to edit and create a rhythm track.
If you need a drum track, you had to record them and then edit them to make a bed track
Today you can purchase loops by some of the renowned players out there. How cool, I can have Omar Hakim (Sting and Peter Gabriel’s drummer) play on my recordings. (Available at Loop loft ).
Here is a rough track I started out with.
