In this Twitch video, while deadmau5 scrolls through his Kontakt libraries starting at 5:58:46, this library is among others in the list
In Eddie's Kontact library, you can see he has Studio Drummer. It's the third from above.
I had this library for a while and hardly used it. But when I did, I realized that I was once again using a quality Kontakt library from Native Instruments who never fail to impress.
