With the rise of clubs like Webster Hall and Gramercy Theater, Irving Plaza has lost its monopoly on concerts by midsize touring bands. What to do? Rename itself! But nobody actually called the club Fillmore New York, so the name reverted to its original form. By any name, it’s a great place to see niche-y vets (Television, GWAR) and buzzy newcomers like Meghan Trainor on their way up to larger spaces. And from the parlor-lit lounge downstairs to the shadowy corners of the balconies, this pleasantly worn old ballroom whispers of New York’s rock past.
