The song was written by Bob Geddins and was a success for Jimmy Wilson in 1953. The song was covered many times after that until Stevie Ray Vaughan got his hands on it in 1982 and released it on his LP "Couldn't stand the Weather". Tin Pan Alley is the name given to the 28th street between Fifth Avenue and Sixth Avenue, between which Broadway runs. Between 1900 and 1930, this was the center of the American music industry and many famous singers and composers were employed here. The song makes no reference to this but focuses on crimes that took place in this area of Manhattan, making it - at least in the song - the toughest area of the city.
Here is a live version with Johnny Copeland...
The blues track is actually very often used for the sound check of loudspeakers. The high dynamics can quickly overwhelm smaller speakers in particular. According to Lars, however, the Soundboard plays the track effortlessly. "Sounds very good" said Lars.
Stevie Ray Vaughan is considered one of the best guitarists and has inspired many people with his blues music, which can be recognized by the fact that, in addition to many awards, October 3 has been declared "Stevie Ray Vaughan Day" for the state of Texas since 1991 and a Stevie Ray Vaughan Memorial Statue was erected in Austin (Texas) in 1994. I dream of "The Beauty of Sound" day 😉
