Hector in my opinion is the best. If you do a search you will find he plays jazz and big band as well; no rock. He is playing since he was 5 years old, concerts at a very young age and has built his own organ.
I heard him take a John Lennen (spelling?) song with variations lasting for 15 minutes; he lead us on a trip of emotions with one song.
I sat in a class where he was teaching how to set up the organ for a particular song, I was amazed; he created the drum parts and all the instrument parts to fit the song.
At an organ concert in Orlando, Fl. he played big band song; in the middle he took a drum solo – both hands and both feet – also fantastic, the diner audience of five hundred people gave him an ovation that lasted over ten minutes. The best organist ever. I have been playing keyboards for years because of this type of player.
No offence to anyone, just my opinion, John C.
