I am a little over halfway through Fundamentals 2 and I was also debating on whether to go to Acoustic or Blues. I'm leaning towards Acoustic because I've already dabbled so much in that area, especially the fingerpicking lessons. But I have really enjoyed playing some of the Made Easy BB King and Eric Clapton songs. The Thrill is Gone by BB King is a super easy 12 bar blues. It sounds SO nice, too. I used it as part of my warm up or just straight playing sessions once I learned it. But I can't play at all now because of my left hand/wrist that may need surgery. So that's a bummer! But I'm still watching the lessons for now.
