Every so often, Billy Corgan plays an intimate acoustic set at Madame ZuZu’s, his Chicago-area teahouse. He’s debuted new music there, he’s played covers there, and now he’s played some more covers there. Last night, he played a solo concert called As-Am-I: Z-0-1 A Set Of Cover Songs, where he played songs like Buddy Holly’s “True Love Ways,” the Mamas & The Papas’ “Look Through My Window,” Skeeter Davis’ “The End Of The World,” and Mark Dinning’s “Teen Angel.” Sierra Swan opened; watch below.
