Context: Stevie Ray Vaughan Memorial is a bronze sculpture of Stevie Ray Vaughan by Ralph Helmick, located at the intersection of Town Lake Hike and Bike Trail (South Bank at South 1st and Riverside Drive) in Austin, Texas, in the United States.  The work was installed in 1994 and is maintained by Austin Parks & Recreation.  Frommer's called the statue "artificial and awkward".  It has become a popular tourist attraction, and often has flowers and other devotions at its base. Family Style is the only studio album by the Vaughan Brothers, released on September 25, 1990.  The album features the brethren guitarists and vocalists, Jimmie and Stevie Ray Vaughan, in their only studio collaboration.  In his early years, Stevie Ray Vaughan often remarked that he would like to do an album with his brother.  He fulfilled that wish in his very last studio performance, which was released nearly a month after his death.  The liner notes end with "Thanks Mama V. for letting us play." Stevie Ray Vaughan's bootleg recordings are performances by Stevie Ray Vaughan that have attained some level of public circulation without being available as a legal release.  The term most often refers to audio recordings, but also includes video performances.  Bootleg recordings arise from a multitude of sources, including broadcast performances, recordings of live shows, test discs, privately distributed copies of demos, and copied studio session tapes.  From the earliest bootlegs in the early 1970s, performances for television, concerts, and studio outtakes have been extensive sources for Stevie Ray Vaughan bootlegs. In Step is the fourth studio album by Stevie Ray Vaughan and Double Trouble released in 1989.  The title "In Step" can be seen as referring to Vaughan's new-found sobriety, following the years of drug and alcohol use that eventually led Vaughan into rehabilitation.  It was also Vaughan's final album with Double Trouble.  In 1990, he recorded a collaboration album with his brother, Jimmie Vaughan, called "Family Style"; later that year, Stevie Ray Vaughan died in a helicopter crash. 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 and one of the greatest guitarists of all time.  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." Hugh Alan Cornwell (born 28 August 1949) is an English musician and singer-songwriter, best known for being the vocalist and guitarist for the punk rock/new wave band the Stranglers from 1974 to 1990. "Lenny" is the tenth and final track on the first Stevie Ray Vaughan album "Texas Flood".  The song is in 4/4 time and notated in the key of E flat major (but instruments are tuned down a half-step).  It is played very slowly and freely, with Vaughan alternating between jazz-inflected chords and solo runs.  The main chord featured in the song is a movable Major 6th chord in which Stevie Ray Vaughan applies moderate vibrato by use of tremolo bar.  The solos incorporate both the E major scale, E minor Pentatonic scale, and E Minor Blues scale.  The style is influenced by Jimi Hendrix ballads like "Little Wing" and "Angel".  The song itself was written and named for his wife at the time, Lenora.  Vaughan also named one of his guitars "Lenny", which he used to play this song and also "Riviera Paradise".  The song was often played at live shows. The Stevie Ray Vaughan Stratocaster is the signature model electric guitar of American guitarist Stevie Ray Vaughan, based on his favorite guitar, Number One.  The guitar debuted at the NAMM Show in January 1992 and began selling at various music stores. Double Trouble is an American blues rock band from Austin, Texas, formed by guitarist/singer Stevie Ray Vaughan in 1978.  The group was active throughout the 1980s and responsible for reviving the blues, inspiring many later blues and rock musicians.  Formed in Austin, Texas, by 1985 the group consisted of Vaughan, Chris Layton (drums), Tommy Shannon (bass), and eventually Reese Wynans (keyboards).  While with Vaughan the band was billed Stevie Ray Vaughan and Double Trouble.  Rooted in blues and rock music, the group worked in many genres ranging from ballads to soul, often incorporating jazz and other elements. The Chessmen were an American garage rock band from Denton, Texas, near Dallas, who were active in the 1960s.  They were one of the most popular bands in the region and recorded for Bismark Records, where they recorded three singles including, "I Need You There", which is now considered a garage rock classic.  The band is notable for including several members who went on to greater fame.  Jimmie Vaughan, brother of Stevie Ray Vaughan was briefly a member, joining after the death of original band leader, guitarist, and vocalist, Robert Patton, who died in a boating accident in 1966.  Drummer Doyle Bramhall later played with and wrote songs for Stevie Ray Vaughan, and Bill Etheridge later played bass with ZZ Top.  Following the breakup of the Chessmen, several of their members, including Jimmie Vaughan, went on to form a group that would come to be known as Texas Storm, which eventually included Stevie Ray Vaughan on bass.
