*Coolio, 47, was so bent at his own concert last week in Minneapolis that he could barely get through his three-song set.

TMZ obtained photos of the train wreck, which took place at The Lounge’s “Hip Hop Thursday” event.

According to Lounge owner Bryan Bell, “Coolio was completely hammered … he was totally vulgar and completely incoherent and I did not want to be there for it” — adding, “This is not what the Lounge does. This is not what we do at our club.”
