i highly recommend the synthetic drums 2 soundbank for B2. it's a pretty stellar collection of sounds from piles of fantastic electronic artists like
funckarma
plaid
einoma
funkstorung
and more. some really amazing and powerfully useful drum sounds in there.
the studio drums collection is pretty good too if you want acoustic drum sounds. they're very expressive and realistic - some of the most convincing 'canned' acoustic drums i've ever heard.
battery 2 is loads of fun. you can do some really wacky and amazing stuff with some of the modulation matrix stuff, and you can make very unique drum sounds and kits. easy as pie to build your own, too.
if you're interested,
check here at audiomidi.com for a pretty in-depth video on all the stuff that's included in Komplete 3 - it gives basic demonstrations of all the NI software that's included. Kinda informative!
rock on,
