I came across this by accident. Its a website for saxophone lessons and techniques by Evan Tate. Ive seen some of his videos before on youtube and have found them very good. You can try the video lessons for free for 7 days, after which you have to pay. Evan offers monthly lessons on subjects such as improvisation, intonation, altissimo, of at least 30 minutes in length with PDF exercises. He also offers the option to contact him via email or SKYPE for any further questions.
