Iggy Pop was one of the most famous punk and psychedelic pop singers of the second part of the twentieth century. He was amazed when he saw The Doors and the special singer Jim Morrison at the university in Michigan.
His first group was The Stooges. He was the singer from the early 70's to 1975.
In my view, he succeeded because of his special and extravagant personality, showed in his concerts and lyrics of his songs.
