I'm not really sure what you're trying to convey, but Mark has shown his guitar abilities at concerts and that is how people were made aware of what he can do. I think being in Creed masked that talent to a degree. I think this next album will prove to everyone how incredible Mark is on guitar. I don't know if you've seen the Ahavo Rabo Taco Salad video, if not, you will get an idea from watching this vid how talented Mark is as well as Myles:
