Not good. Bad.

The early Jazz musicians would say that a guy could really "Blow" if he had a good sound when playing the horn. If he couldn't play very well then they would say that he was "Sucking" on that horn. That's where the term "Suck" as being something bad came from.
He plays that horn so poorly that he must be sucking on it.

He doesn't blow, he sucks.
