Ock Soo Park, A Korean preacher who always do Gospel Rally in Madison Square Garden in NYC.
I just need to note this down because I forget his name whenever I needed to mention it.
I attended his crusade once. Good music group, but message was somewhat bland in the sense that it focused more on preaching moral than Christ. It was a couple of years ago, I may not remember as well, but that was my impression of him. Their outreach however, was incredibly active in the city.

07/10/2010 Addition:
Some have claimed that Ock Soo Park's ministry (Good News Mission) is well known as cult in Korea: That they believe their church is the only path and that one need not ask for forgiveness to obtain salvation.
I have read their statement of faith. From what I can tell, it is contrary to others' claim for a cult. Nonetheless, because some of the statements are vague in regards to certain questions such as "if their church is the only church to heaven" in their "Church" statement section, comparing to one of the forum posts claiming that the pastor told him vaguely that there are churches with problems with interpretation but his church has the word of God. It would appear that their statement of faith is a mixture of Predestination, apostle's creed and dispensational premillennialism. If this church practices cult doctrine as claimed by some, then they are doing a very good job at hiding them.
Of course, some of the relatively "new" cults that I've encoutered are very good at covering up their "differences" with orthodox doctrines, unlike the older cults such as the Mormons or the Jehovah Witnesses which I give credit here for being honest. These cults cover up even to the point of lying not to exhibit lying as a moral value, but they knew and fear of the reactions from others, thus they compromise the truth, in order to "save" others. A despicable act, which is also seen in mainstream shallow Chrsitians sometimes.
