Seems like I remember you posting up a while back, it was one of the fastest while being accurate post I had seen posted here. If so you have lost no speed and greatly increased your bag of tricks, while still being quite accurate. I would like to hear an example of you using them to a backing track again.
After listening to the first track for a couple minutes (my taste in music) I started to feel like I was being yelled at, so much so fast just kept coming, without softer slower spots to let me unwind. Of course not having backing track didn't help. I know there is music out there that that is the goal. If that is what your after go chase it, your skills are ready.
When you practicing some of those tricks do you ever pick softer going in one direction than the other repeatedly? I think you could add some really cool textures.
Thanks for posting.
