Yes it is O.G. Style not with an 'S. I know because he was a friend of mine and I got the original tape. I must give credit to Mastermix crew (out of respect for ESP, fuck Jonnie Freeze who steals others releases and re-uploads them), they posted this mix first, but the quality was bad, parts would duck out with the audio and the clarity was muffled. I hope you enjoy the quality here. I worked on it for awhile.
