Rachelle Ferrell has the type of vocal range that makes other singers green with envy.
The Pennsylvania native boasts an amazing six-octave range. And Ferrell most definitely puts her range to good use, masterfully handling a variety of pop, jazz and R&B material.
She's put together quite a career as a backing vocalist, having supported such acts as Vanessa Williams and George Duke over the years, but she's also an accomplished solo artist.
Ferrell will showcase her one-in-a-million voice when she performs this weekend at Yoshi's San Francisco, 1330 Fillmore St. Showtimes are 8 and 10 p.m. July 6-7 and 7 and 9 p.m. July 8.
Tickets are $25-$35 at www.yoshis.com.
