Some context: Stephen Ray Vaughan (October 3, 1954 - August 27, 1990) was an American musician, singer, songwriter, and record producer. In spite of a short-lived mainstream career spanning seven years, he was one of the most influential guitarists in the revival of blues in the 1980s. AllMusic describes him as "a rocking powerhouse of a guitarist who gave blues a burst of momentum in the '80s, with influence still felt long after his tragic death." Born and raised in Dallas, Texas, Vaughan began playing guitar at the age of seven, inspired by his older brother Jimmie.
In May 1969, after leaving the Brooklyn Underground, Vaughan joined a band called the Southern Distributor. He had learned The Yardbirds' "Jeff's Boogie" and played the song at the audition. Mike Steinbach, the group's drummer, commented: "The kid was fourteen. We auditioned him on 'Jeff's Boogie,' really fast instrumental guitar, and he played it note for note." Although they played pop rock covers, Vaughan conveyed his interest in the addition of blues songs to the group's repertoire; he was told that he wouldn't earn a living playing blues music and the band parted ways. Later that year, bassist Tommy Shannon walked into a Dallas club and heard Vaughan playing guitar. Fascinated by the skillful playing, which he described as "incredible even then", Shannon borrowed a bass guitar and the two jammed. Within a few years, they began performing together in a band called Krackerjack.  In February 1970, Vaughan joined a band called Liberation, which was a nine-piece group with a horn section. Having spent the past month briefly playing bass with Jimmie in Texas Storm, he had originally auditioned as bassist. Impressed by Vaughan's guitar playing, Scott Phares, the group's original guitarist, modestly became the bassist. In mid-1970, they performed at the Adolphus Hotel in downtown Dallas, where ZZ Top asked them to perform. During Liberation's break, Vaughan jammed with ZZ Top on the Nightcaps song "Thunderbird". Phares later described the performance: "They tore the house down. It was awesome. It was one of those magical evenings. Stevie fit in like a glove on a hand."  Attending Justin F. Kimball High School during the early 1970s, Vaughan's late-night gigs contributed to his neglect in his studies, including music theory; he would often sleep during class. His musical career pursuit was disapproved by many of the school's administrators, but he was also encouraged by many people to strive for a career in art, including his art teacher. In his sophomore year, he attended an evening class for experimental art at Southern Methodist University, but bailed when it conflicted with rehearsal. Vaughan later spoke of his dislike of the school and stated that he had to receive a daily note from the principal about his grooming.
what else did he do at this time?
A: rehearsal.
Some context: Sia Kate Isobelle Furler (; born 18 December 1975) is an Australian singer-songwriter, record producer and music video director. She started her career as a singer in the local Adelaide acid jazz band Crisp in the mid-1990s. In 1997, when Crisp disbanded, she released her debut studio album titled OnlySee in Australia. She then moved to London, England, and provided lead vocals for the British duo Zero 7.
After Crisp disbanded in 1997, Sia moved to London, where she performed as a background vocalist for British band Jamiroquai. She also provided lead vocals for English downtempo group Zero 7 on their first three studio albums and toured with the group. On Zero 7's 2001 album Simple Things, Sia contributed vocals to two tracks: "Destiny" and "Distractions." The single "Destiny" peaked at No. 30 on the UK Singles Chart. In 2004, she provided vocals for Zero 7 on "Somersault" and "Speed Dial No. 2" (from the album When It Falls). In 2006, Sia again collaborated with Zero 7 for the group's third album, The Garden and hence she is regarded as the "unofficial" lead singer of Zero 7.  In 2000, Sia signed a recording contract with Sony Music's sub-label Dance Pool and released her first single, "Taken for Granted", which peaked at No. 10 on the UK Singles Chart. In 2001, she released her second solo album, Healing Is Difficult, which blends retro jazz and soul music and lyrically discusses Sia's dealing with the death of her first love affair. Displeased with the promotion of the album, Sia fired her manager, left Sony Music and signed with Go! Beat, a subsidiary of Universal Music Group (UMG). At the APRA Awards of 2002, Sia won the Breakthrough Songwriter category alongside Brisbane pop duo Aneiki's Jennifer Waite and Grant Wallis.  In 2004, Sia released her third studio album, Colour the Small One. The album employs a mixture of acoustic instruments and electronic backing to her material. The album spawned four singles: "Don't Bring Me Down", "Breathe Me", "Where I Belong" and "Numb". "Breathe Me" peaked at No. 71 in the United Kingdom, No. 19 in Denmark and No. 81 in France. "Where I Belong" was scheduled to be included on the soundtrack for the film Spider-Man 2; however, owing to a record label conflict, it was withdrawn at the last minute.  Dissatisfied with Colour the Small One's being poorly marketed and struggling to connect with a mainstream audience, Sia relocated to New York City in 2005. During that time, "Breathe Me" appeared in the final scene of the U.S. HBO television series Six Feet Under, which helped increase Sia's fame in the United States. Consequently, Sia's manager, David Enthoven, set up a tour across the country to maintain her career.
