The music world was rocked last night as news of the death at age 90 of iconic originator Chuck Berry spread over the internet. Berry’s monumental influence on generations of guitarists and bands is hard to measure, but not to quantify in importance to music. Chuck personally led to the wide-spread love and understanding of rock and roll through a string of hit songs and other anthems championing the nascent genre in the early 1950s. He died near his home of St. Charles County, MO and his death was confirmed by the St. Charles County, Mo., police department.
