Hi Thorin, I dont know why,I guess is to get lot's of different sounds,That Drummer Richard Baxter has 5 drum kit's here is the links to all the drum kit's http://www.richardbaxterdrums.com/ne...s?idPage=drums

One thing i know is that i got his CD at Tower Records and i like it a lot.you can hear 2 MP3's from the Cd on his website
