You’ve got the piercings, the leather pants, and a gnarly air-drum routine. Now all you need for rock stardom is to learn a chord progression. Hey, don’t go giving up on the rock ’n’ roll fantasy just yet. Head to the newly opened Revolution Rock Bar, where you and your backup singers can retreat to a seductively dark, glossy space. Better than any green room, this hangout’s got leather banquettes, cattle skulls, tables adorned with laminated concert photos, and song lyrics graffitied on the ceiling. There’s also plenty of post-performance noshing — like lobster-and-crab cakes, wood-grilled pizzas, greasy burgers, and lyrical entrees like grilled swordfish with lemon-herb butter and tomato-and-ginger concassé. Bonus: Your brooding, tattooed drummer can mellow out with a rum-based Jane’s Addiction cocktail. The club cranks things up with live performers three nights a week while DJs hit the smaller, downstairs lounge on weekends. One night here and you’ll be channeling Bowie. So now all you need is a hotel room to trash. Revolution Rock Bar, 200 High Street, Downtown (617-261-4200 or revolutionrockbar.com).
