What raged in the '90s - the post-Zeppelin grunge-metal of Soundgarden, the crepuscular industrial firestorm of Nine Inch Nails - still seethes today. Each act's latest album (Soundgarden's King Animal of 2012 and Nine Inch Nails' Hesitation Marks of 2013) is a crisp representation of the past refreshed for the present. Wednesday night's concert featuring both bands at Camden's Susquehanna Bank Center suggested that that present has a bright future.
Soundgarden lead vocalist Chris Cornell sounded fresh and forward-looking. In 2007 he strained his vocal cords, and ever since he has relied heavily on his lower register to convey his lyrical mix of wonderment and disgust. On Wednesday though, Cornell's squeals and screeches put Robert Plant to shame as the singer made his way through Soundgarden's finest tracks. "Black Hole Sun" and "Superunknown" allowed Cornell to prowl around his lower register with falsetto blasts. Numbers such as "Outshined" and the herky-jerky "Let Me Drown" opened the gates to his full-bodied high register.
