Billy Corgan will play his first solo show on April 19 at the Metro, Billboard reports. Tickets are not yet on sale, so if you want to go, you better keep your eye out -- they're likely to sell out in a matter of minutes. Meanwhile, Corgan writes on his blog (3.12.04 entry) that he's planning a unique form of fan appreciation: visitors to his site will be informed of a place and time to show up, present ID that they're over 18, and will then get to sit in on recording sessions the week prior to the premier concert.
