Music portal ArtistDirect has teamed with online auction site eBay to offer concert tickets and music memorabilia to Netizens. Currently up for bid are front-row seats to concerts by the Who and items from k.d. lang and Stone Temple Pilots, for example. Proceeds from the ticket auction will go to charity. In the future, the Netco wants to offer “experiences” for auction, like guitar lessons from a top musician or the chance to be a roadie for a day.
