There's no difference in a lot of people's minds between good musicians and popular musicians.

For me, the most difficult thing is that I am learning melodies on guitar from some songs whose melodies were not meant to be played on guitar. Ever. They were intended mostly for keyboards or melodic percussion.

I started touring in 2006, and there was an agreement made for merchandise between my mom and myself.

I didn't really hear any other music other than what my dad was working on until I was 12. My recollection of hearing other music was that I liked some things that I heard but I always thought, 'Where's the rest of it?' It didn't have the same amount of detail or instrumentation or imagination in the arrangements.

There are so many things that are misunderstood or not recognized about my father's music because they've been filtered by people who work for magazines like Rolling Stone.

While it is true that Frank had a great sense of humor, he was also very serious about composing music. In reality there are only a handful of skilled players who can play his most complex pieces. It takes a lot of patience to learn and requires a fantastic memory.

I was given all of my dad's guitars when he passed, and they were being stored at the house. My mother decided they were hers again, and she took them all back, and now they're going up for auction.
