“Mr. Brownstone” is a song written by American rock band Guns N’ Roses. It appears on their 1987 album Appetite for Destruction. Slash relates that the song was begun by him and Izzy Stradlin while they were at Izzy and his girlfriend Desi’s apartment. He states that they were sitting around, complaining about being heroin addicts, when they started improvising lyrics and music (“Brownstone” is a slang term for heroin). The lyrics make a clear reference to the tolerance that the drug causes in the verse that says:”I used to do a little, but a little wouldn’t do, so the little got more and more. I just keep trying to get a little better, said a little better than before”. When they had the lyrics all together, they wrote it down on the back of a grocery bag and brought it to Axl Rose. Slash said the lyrics describe a typical day in the life of Slash and Izzy. He also states that it was the first song the band wrote after being signed by Geffen Records.
