There are plenty of examples of musicians who have achieved some success, either solo or in a band, then later on joined some other established band:
Bill Bruford started out with Yes, then later joined King Crimson, an already-known entity
Ronnie James Dio rose to fame in Rainbow, then later joined Black Sabbath
Sammy Hagar became known via Montrose, and later joined Van Halen
There are many more examples. But what musicians have become known, and then during the course of their career, joined two or more already established bands?
Going solo, forming a new band, or forming a supergroup with other known musicians, is not what I’m looking for. I’m interested in musicians who have joined up with bands that were already in existence, and had some measure of success. An “established” band can’t really be well-defined, I know. I’m thinking of bands that have at least put out an album, and have had some success outside their home city.
After King Crimson dissolved in the mid-70s, Bruford and John Wetton joined up with Alan Holdsworth and Eddie Jobson and formed the band UK. Later still, he formed a couple of his own bands. These do not qualify as joining an established band. I suppose an argument could be made that he “joined” Genesis at one point, for a short time, but he was a touring member only, and appeared on very few released live recordings.
Dio started out in Elf before joining Rainbow. But Rainbow doesn’t count, because he was an original member of the band when Ritchie Blackmore formed it. After Black Sabbath, Dio formed his own band. Regardless of where Dio actually got his start, the only established band he joined after becoming famous was Black Sabbath. (Don’t tell me about Heaven and Hell, it’s the same band. :p)
Sammy Hagar went solo after Montrose… doesn’t count. Formed the supergroup HSAS with other musicians… doesn’t count. Formed the supergroup Chickenfoot with other musicians… doesn’t count.
So… who has joined two or more established bands over the course of their career? Maybe we can figure out who “wins,” having joined the most bands.
To start things off, my contribution is Steve Morse.
Morse got started with the Dixie Dregs. In the '80s, he joined Kansas for a couple of albums. In the '90s, he joined Deep Purple, and is with them to this day.
