Chris Cornell was a rock musician who served as the lead vocalist and rhythm guitarist for the band ‘Soundgarden.’ He also served as a vocalist for the band ‘Audioslave.’ He was also the founder and front-man of the band ‘Temple of the Dog,’ which was formed as a tribute to his friend, Andrew Wood. In addition, he had released several solo studio albums. An innovator who resisted genre labels, Cornell was widely regarded as the chief architect of the 1990s grunge movement. Once ranked as ‘one of the best voices in music history,’ he successfully maintained his own unique identity. What made his songs distinct was the usage of non-standard chord progressions as he did not stick to one diatonic scale. Even for a short sequence, he used to change the keys several times. Though he did not change his style during his early career for ‘Soundgarden,’ he later switched to a more conventional style with short interludes. Throughout his career, which spanned for more than two decades, he was nominated for the prestigious ‘Grammy Award’ several times. He was also nominated for other awards, and won quite a few of them. He was associated with many charitable organizations, particularly in the fields of education and child rights.
