Hello everyone!

I need help with regards to the core training specifically blues and rock. I am aiming to be able to play a solo or improvise on licks so I practice on the two courses as I really like both genres. I really practice the licks and try to understand what I can(root note, repetition, rhythm). However when its time to improvise on the lick and play together with Anders Mouridsen, I just can'tseem to keep up. So I move on to the next lick that he is going to teach without being able to really jam and improvise on the lick. I then try to improvise on all the licks that i have learned but I fail.

My question is, should I keep learning new concepts and licks? Or should I stick to one lesson/lick until I am comfortable with it?
