Elvis Costello may be saying goodbye to plastic, round, silver discs as a medium for music distribution. His forthcoming Momofuku will arrive April 22 only on vinyl, with a digital download code included within the package. No other details are available concerning the follow-up to 2004’s Delivery Man, but Costello himself will open for The Police on their summer tour which begins May 10 in Chicago.http://www.billboard.com/bbcom/news/article_display.jsp?vnu_content_id=1003728188
