The 9:30 Club was absolutely packed Wednesday night for the D.C. debut of Them Crooked Vultures, a recently-formed hard-rock “supergroup” featuring Dave Grohl of Nirvana and Foo Fighters fame, Queens of the Stone Age frontman Josh Homme, and multi-instrumentalist John Paul Jones, who formerly played bass in a little band called Led Zeppelin. Joined by touring guitarist Alain Johannes, the high-profile trio treated the crowd to an impressive 90-minute set, more than justifying the hype that made this one of the most highly-anticipated shows of the year.
