He’s a fantastic player, i’ve listened to a lot of sax players on youtube play rock & roll, and most of them can’t belt it out in true rock & roll style. If it wasn’t for Johnny’s altissimo course, i still wouldn’t be able to play altissimo notes. The main factor with courses and music lessons, you have to put the work in, to get results. I’ve been playing 4 yrs now and stuck with it, i’m not the best average player in the world, but the music sheets that i can play now, i wouldn’t have dreampt of attempting them years ago. The challenge to keep going, cause theres harder sheets on the horizon, which sound fantastic, if only i could play them. But in our street, i’m the worlds best sax player (the only sax player in the street, so i can claim the street title.. lol)
