Top 10 Musicians Who Played for Two or More Thrash Metal Bands

There was a frequent unintended rotation mainly of members of Exodus, Slayer and Testament that was even funny at times. Here's an example:

In 2005, Tom Hunting left Exodus. Hunting was replaced with drummer Paul Bostaph, who left Slayer because ex-Slayer drummer Dave Lombardo rejoined Slayer. Later, in 2007, Hunting rejoined Exodus when Bostaph left Exodus to rejoin Testament. Hunting has said that he is great friends with Bostaph.
