At last, ye wizards, witches and hapless muggles: The blessed day is nigh. No, it’s not Walpurgisnacht again; thanks to the Tacoma Public Library, wizard rock concerts are the new Sabbats.

The Main Library will host The Parselmouths, Seattle youngsters Kristina Horner and Brittany Vahlberg who took the name for the wizards who can speak the language of snakes and rock in the name of the Slytherin girls of Hogwarts, Friday as they unleash songs from their new album, Sssss.

It will be Potter-rific. 

I have sunk to my new low. â€" Suzy Stump
