The Legends Of Music on Instagram: "Stone Temple Pilots performing “Sour Girl” Live on the Jay Leno Show in 2000 “Sour Girl” is the moment STP stopped pretending they were going to survive the ’90s and finally admitted what it cost to even try. People hear the sweetness, the acoustic shimmer, the radio polish, the melody that goes down easy, and convince themselves this is the band at their softest. That’s the lie. This is STP at their most shattered, and its placement on No. 4 isn’t a breather.
