(Gibson) We've nearly arrived again at that most American of holidays: the Fourth of July. In celebration of the country's independence, and legacy of amazing bands, Gibson.com is counting down the Top 50 American Rock Bands of All Time. Today they list their picks for no 41-50. Here are a couple highlights:49. Frank Zappa and the Mothers of Invention: Frank Zappa was undeniably a creative genius, and part of this genius was expressed in his ability to surround himself with unique musicians. The original Mothers of Invention encapsulated the dirtier side of the '60s, yet were equally capable of off-key darkness ("Who are the Brain Police") and note-perfect pop ("You Didn't Try to Call Me"). Frank eventually found more musically able Mothers, but the original lineup had an almost naive charm that couldn't be replaced. – Peter Hodgson
42. Cheap Trick: Although they first made it big in Japan, these preeminent purveyors of power pop are a uniquely American force. Fans have been surrendering to Cheap Trick's sizzling brand of super-melodic rock for more than 30 years. Why? Because few songwriters exist that are as strange, clever and enthralling as Rick Nielsen, few groups can claim a "Man of 1,000 Voices" like Robin Zander and no band – ever! – has worked as hard on stage to be so consistently entertaining. – Bryan Wawzenek more on this story
