Terri Hendrix is a singer-songwriter, multi-instrumentalist, and independent artist from Martindale, Texas, on the outskirts of San Marcos, Texas, who has been writing and performing an eclectic mix of Americana genre, encompassing folk, pop, country, blues, and jazz, since 1990. Hendrix has released at least 18 albums and EPs on her own Wilory Records label, co-wrote the Grammy-winning song "Lil' Jack Slade" by the Dixie Chicks, and, in 2011, published a book, Cry Til You Laugh – The Part That Ain't Art. As of 2021, Lloyd Maines, on guitars, has accompanied Terri Hendrix live and in recordings since 1997 and her second album.
Known for her live shows and positive energy, Hendrix says she lives by the adage "own your own universe," a lyric from one of her earliest songs. In addition to writing and performing, Hendrix conducts songwriting workshops both inside and outside of Texas, and has established a nonprofit community arts center in the San Marcos area, the OYOU ("Own Your Own Universe"), offering educational and therapeutic arts programs, including for those who face neurological challenges or physical disabilities.
