Finding a brush kit that I felt sounded good and authentically 'brushy' enough for me when used with non-jazz MIDI beats has been a long standing quest for me. I am also an EZDrummer user and Toontrack recently offered the Nashville EZX expansion for something like $39 so I bought it. The brush kit in this set sounds the best to me by far no matter what the beat I have applied to it. It sounds like brushes on the snare and it sounds like brushes on the cymbals.
Normally, I have preferred the sound of the AD drums, but preferred the beats available from EZ Drummer, at least for the music I do. The ability to shape the sound of the AD drums is nice, and the ability to modify the beats in EZDrummer 2 provides the best of both. However, this Nashville kit has changed that formula for the brush kit.
