Well, we've got you covered!
Personally, I began learning to DJ in the early 1990s, and have played dozens of parties, club & dance nights, and raves, using everything from traditional turntables, to the very latest in DJ technology.
I have also taught a host of DJs in years past, and was a school teacher for close to a decade, which led me to create this virtual classroom, for my own son, who more recently wishes to learn, but lives hundreds of miles away from me (as a young grad school-aged adult).
Watch and learn from pros like DJs TLM (The Last Mohican), Johnathan Ellaskins, Brian S. Redd, Sound Of Arman, DJ Tutors, Digital DJ Tips, DJ Tech Tools, Dubspot, and many others, break down the essentials, more advanced techniques, and various insights to DJing, and thriving in that particular industry, as a self-sufficient club, or mobile DJ.

Practice, and enjoy!
