Have a lot of faves like Genesis, Led Zeppilen, etc. But sorry, on one comes close to the Beatles. I'll admit that they came along just when I was most receptive to music in my adolescence.
But their music still stands the test. While people like Chuck Berry and Elvis opened the doors to rock and roll, the Beatles perfected it and open up more doors for many bands that have come (and gone), and the eventual evolution of rock music.
The Beatles came into this country with incredible expectations. And they more than met the challenge.
Not only did the Beatles do it musically, they changed us socially, (long hair for example), politically, style-wise, and every other which way. There may never be another band like the Beatles, although I certainly hope there will be. The music world needs another one badly.
