What is DJ-ing? Many uninformed people will dismiss it as simply "playing other people's music." I think it is far more than that. It's an art unto itself and it has just as much to do with connecting with people as with the music itself.
DJ's throughout time have all used records as a way to channel the energy of the crowd through their music and vice versa. From Grandmaster Flash to Andy C. A DJ has a world of music at his disposal with which to create a musical quilt. Like a master chef, a good DJ applies just the right amount of ingredients to make a perfect meal. It is not simply playing other people's music; it's taking that music and using it to create a musical journey, to establish unexpected connections between pieces of music (sometimes of entirely different genres), and to surprise and delight
the listener. In a way, a DJ can dig a lot deeper and surprise more than a live band.
I used the word "records" up above, but I am using it generally and not specifically referring to vinyl or acetate records and dub plates. I think CD's (although practicaly obsolete), MP3's and other digital tools are a perfectly acceptable way to bring music to the masses, although I do think vinyl sounds better.
DJ-ing is one of my favorite art forms, and although I cannot DJ myself, I can spin records in my head.
My current favorite DJ's are Spor and the Streetlife DJ's.
