The frenzy over Book 7 [of the Harry Potter series] has propelled wizard rock to these heights. The bands have tens of thousands of friends on MySpace, with Harry and the Potters approaching 100,000. Maggiacomo has released two CDs. Draco and the Malfoys just finished their second CD, and later this month will join Harry and the Potters on a tour of the East Coast, Midwest and Ontario. Other bands, including the L.A.-based Remus Lupins and the Seattle-based Parselmouths, are on tour.
