The creative tension within the band boiled over during the "1984" tour, with Eddie Van Halen and original frontman David Lee Roth falling out. Roth left the band in April 1985.
One of his gripes with the guitarist was reportedly the rocker's outside work that included providing the lead-in guitar for Michael Jackson's 1983 smash hit "Beat It."
However, Van Halen announced a reunion tour in 2007 with Roth performing with the group for the first time in 22 years.
Another tour planned in 2012 had to be canceled after Eddie Van Halen had to undergo emergency surgery.

But the band reunited again in 2015 for an extensive North American tour.
The legendary guitarist was known to have health problems that would interfere with his work for years.
He underwent hip surgery in 1999 and had part of his tongue removed in 2000 after being diagnosed with cancer, likely because of heavy smoking.
Although he was declared cancer-free following the surgery, the American tabloid news site TMZ reported earlier this year that he had been going to Germany for throat cancer treatment.
His drug abuse and heavy drinking contributed to his 2007 divorce from TV actress Valerie Bertinelli after 16 years of marriage.

Tributes from some of the biggest names in the music world poured in Tuesday following news of his death.
