Audioslave was a $$supergroup$,$ consisting in part of members from Soundgarden $($rip

Chris Cornell$)$ and Rage Against the Machine. In fact, many musicians play with different

bands throughout their career and many bands change members over time $($Black

Sabbath had both Ozzy and Dio lead them at different times$).$ We will use a MusicianID

to identify band members and also capture their name, vocal range and main

instrument played. Bands each have a unique name and we will capture their formation

date, last active tour and if they are still together. We are not tracking musicians who

have not been part of a band. We will capture date of the first time a musician was with

a band and the last time that musician was with a band
