"He's the most talented person I ever worked with because he was talented in so many different ways. He's a guitar player and a lead singer and he wrote all the songs. He did everything for Nirvana that it took Jimmy Page and Robert Plant to do for Led Zeppelin. Kurt also designed the album covers and wrote treatments for the videos. He even designed the t-shirts. He was really a comprehensive genius when it came to the art of rock and roll."
