Great idea and execution. Hy2rogen always provides the best quality work. These are full kits of breakdown sections. Basically a full track without main drums. You can create that part on your own using what is given to you. This is very large size for something like this because he gives every sound broken down in detail. The sounds are elaborately created, not a bunch of tech sounds thrown together- which shows the quality of what you get with a set from Hy2rogen. You also get a folder in each set of certain dry sounds in case you don't want to use the effected version. These kits feel right at home on any huge mainstage festival.
