Long version of Texas Flood by stevie ray vaughn ! Texas Flood is an electric blues album by blues guitarist Stevie Ray Vaughan and his band Double Trouble, released in 1983.
Although "Texas Flood" has three verses of lyrics, the song is more of a prolonged guitar solo, allowing Vaughan to show off his characteristic electric blues style. During live shows, he would often play portions of this song behind his back, arousing an enthusiastic crowd response. Stylistically, "Texas Flood" is structured around the common three chord blues progression. Written and performed in the key of G (sounding F# because of Vaughan's tuning), it is in 12/8 time, or compound time[1], which gives it a "slow burning" feel that is common in Texas blues.
