Our Ideas and Additional Information:
Since this is a logo for Shaquille and his DJ Brand maybe a hint of music, headphones, mixers, EQ etc....
The uploaded photos are not for the logo, more to show you DJ DIESEL so you can create a logo to fit his likeness.
And if it doesnt make the logo look to busy possible a very small reference to basketball? This may or may not work??
Shaq is going with the nickname DIESEL with his DJ brand.. When I think of Shaq and DJ Diesel i think of describing words like POWER, STRENGTH, SIZE, INDUSTRIAL, STEEL
