In all my CDs I have used as the foundation drums a product called Drums on Demand. These are professional recorded drum loops in which you assemble in your recording software to create a drum track. They offer about 12 DVDs full of loops and I have all of them.
Basically as you open the DVD there will be many sub directories each with a name of a certain groove. Within that groove you will have many wave files cleaverly named such as "intro" "intro alt" "Verse" "Verso Crash" "Verso Ride " and so on. This helps you select the loop you want. It is like putting together a puzzle but the results are excellent. Many time the drums come out perfect and other times I will use my Yamaha drums to add additional fills or hits.
Anyways if you are confused how to get great sounding drums into your recordings without a drummer, Drums on Demand is the answer.
Here is their web site where you can demo many of their DVDs they sell.
