Pink Floyd’s legendary guitarist, David Gilmour, is playing some shows at Radio City Music Hall (April 10) and Madison Square Garden (April 11, 12), but let’s face it, those accursed ticket scalpers have made your attendance about as likely as pigs on the wing. Who knows, maybe he’ll dedicate “Wish You Were Here” to all the fans who couldn’t afford to buy a ticket. But hey, who needs to watch Gilmour be ever so careful with that axe– his mind-bending music will be way more affordable at these upcoming trip-out sessions.

Coney Island Laser Shows: The Dark Side of the Moon
Feb. 6, 10 p.m., at 1208 Surf Ave., Coney Island; tickets $15.
This experience at the Coney Island Circus Sideshow’s bare-bones theater is a far cry from being comfortably numb in a plush, reclining planetarium seat. But the cheapo 3D glasses go a surprisingly long way in creating a momentary lapse of reason as laser animations run like hell before your eyes. Best of all, included in the price of admission is a bumper-car ride at Eldorado Bumper Skooter and performances by the likes of Serpentina and her albino python.

Pink Floyd Laser Spectacular
March 2, 7 p.m., at Gramercy Theatre, 127 East 23rd St., Gramercy; tickets $26.50.
The one thing Boston has over New York is the Floyd laser show at the Hayden Planetarium (alas, despite a planetarium upgrade, the Museum of Natural History won’t be bringing back its shows). But, whatever, we occasionally get visitors like the Spectacular, a pioneer of the genre. Thirty years strong, it claims to be the world’s longest touring laser show. Shine on, you crazy diamond!

The Machine
April 22 , 8 p.m., at Brooklyn Bowl, 61 Wythe Ave., Williamsburg; tickets $15. 
For over two decades, these guys have been one of the country’s top Floyd tribute acts, going to great lengths to recreate the band’s elaborate stage sets, light shows, and epic wall-of-sound jams. Their knowledge of Floyd’s repertoire runs deep, so you won’t have to settle for the usual cuts off The Wall and Dark Side. Just know that they draw the line at making a dog sing.
