When I saw a crystal method video on youtube, (Check it out by typing in m-audio), they talked about how they liked to "gritty-up"" or "dirty up" their tracks. When I saw this video, I immediately copped IZotpe trash and have been experimented with this plug in.
Trash is just a plug in that distorts/reduces the bit sounds/turns any clean digital sound into a "grimier" one.
trash is good for dirtyin up your drums also if you wanna make electronic sounding drums, guess it depends on the style of music u make weather u'll deem it worthwhile, if your adventurous with your drums its great!
