I have purchased ALL of Radovan Vlatkovic's videos. I have used his video as reference materail to the solos I am working. I have made more progress watching these videos. THese an education by themselves. Any horn at any level will learn and take something of benefit away from any of these videos watched. Theses vidoes demonstrate what right looks and sounds like. Radovan sir, please produce more along with Playwith a PRO!!!!
