The phrase "children should be seen and not heard" was coined by the Invisible Man, who was sick of tripping over his progeny. Stick it to the Invisible Man with today’s Groupon: for $50, rockers ages 7 and up get four, 30-minute introductory music lessons at School of Rock, located on 9th Avenue in Midtown West (a $200 value).

With 58 schools in 23 states, the inspiring and performance-driven School of Rock enthusiastically infuses fledgling tunesmiths across the nation with the rhythm, skill, and confidence required to rock 'n' roll. Each instructor at the school is a professional musician, and fully equipped with the know-how to catapult instrumentalists to the crest of Mount Rockmore.

Aspiring rockers ages 7 and up can choose instruction in guitar, drums, keyboards, bass guitar, or vocals, ignoring such fringe instruments as the mega-accordion and rotoflute. Graduates of School of Rock have formed bands, thrilled fans, and sauntered across stages without being chased by security guards or irate Hamlets.
