Without a doubt all modern bass players owe a debt to the brilliant Charlie Mingus. Even when they don't know who he was, never heard his name, they've learned from him by 3rd and 4th generation musicians who may also not be directly influenced by Charlie, but those who followed those who followed Charlie. Listen to him and you too will recognize the genius and his influence.
Here is an excerpt from Charlie's greatest work:
Charlie gained a place for himself as a man who wandered the streets late at night, for days at time, unwashed, in the same clothes, old pajamas and a robe, with those who saw him during his wanderings concluding he was a heroin addict or an alcoholic. Police recognized Charlie was harmless, and often escorted him home to his frantic wife, who had called police many times in pursuit of Charlie. Charlie, most of the time wasn't drunk or high on smack, he was deep into his own mind, hearing his music and composing more. Some might say was insane, and after one multi day of wandering in the streets, his wife, with help from two friendly police officers, escorted Charlie to Bellevue for a psychiatric exam, for his own good. A young resident working at Bellevue then, had a father who participated at Columbia University with the evaluation of Albert Einstein's intelligence. He borrowed tools from his father, and put Charlie to the test. Charlie's mind was so far developed with the ability to quantify the mathematical and symbolic abilities to theorize on a level unknown by most people that he was judged to be more intelligent than Albert, and likely to be equally capable of theorizing the Quantum physics Albert had suggested. His own mind tortured Charlie with his abilities to see what we mere mortals don't. Charlies was released from Bellevue as not insane, but beyond understanding.
Learn a bit more about Charlie, and as far as I know this is the only place online where Epitaph as performed after his death is available, for you, if you have the courage, the fortitude and the desire to be a far better musician than you are, study Charlie's great opus, his symphony Epitaph.

When Jack Bruce played with Cream, the media pegged him as the greatest bass player the world had ever heard. Jack shrugged, and simply said "Mingus."
