Garcia returned to San Francisco. He spent time teaching acoustic guitar and playing bluegrass music. He met up with poet Robert Hunter. Together they started playing in the city's coffeehouses. Hunter later became the lyricist for the Grateful Dead and Garcia's lifelong songwriting partner. Garcia started becoming famous around San Francisco between 1962 and 1964. He was known for his Folk and bluegrass performances. Garcia tried a new drug LSD for the first time in 1964. From that time on he became a lifelong advocate of psychedelic drugs. Musically he began experimenting outside the basic folk music formula and trying out new styles of music. This included jug band, Mother McCree's Uptown Jug Champions. A year later they changed their name to the "Warlocks".
