Janis Joplin
Ian Anderson (Tull)
He (Ian) made the flute a rock and roll instrument.Fun fact. Jethro Tull were so bad in their early days that they had to keep changing their name and pretending to be a new band to get bookings. "Jethro Tull" just happened to be the name they were using the first time a promoter called them back for a repeat appearance.
(this is honestly the first thing I thought of)
