"Nevermind," "In Utero," and "MTV Unplugged" are soon to be released on 180-gram, audiophile quality vinyl for the very first time.  Sub Pop is already working on the vinyl release for "Bleach," Nirvana's first album.  Senior VP of Universal stated, "They're the best sounding records on the market......We spend $15 per LP on manufacturing. That's an enormous expense, but it shows in the final product, it shows by our sales, it shows by our growing customer base."
