Has there ever been a singer that's had a more impressive resume within the genre where he performed? Ronnie James Dio was a true metal icon who showed off his range and talent performing with such acts as Elf, Rainbow, Black Sabbath, Heaven & Hell and his own self-titled band, Dio.

It's hard to imagine that the man who began his love of music playing the French horn and trumpet would eventually be the person often credited with creating the now standard "devil horns" sign at metal shows. Even though he was a man of diminutive stature, there may not have been a bigger giant when it came to performing onstage as his personality and passion always shone through.

After his death from stomach cancer in 2010, there was an outpouring of love not only from the metal community, but from musicians and entertainers across all genres and outlets. It speaks volumes that two years later, there are still many that have taken the time today to keep his memory alive by sharing their thoughts on the anniversary of his death (May 16).
