Short answers, pulled from the story.
Aerosmith formed in 1970 when five musicians gathered in Boston to forge a new sound that would eventually define American hard rock. The group moved into a shared home at 1325 Commonwealth Avenue in Boston to write and rehearse music together.
The band consisted of Steven Tyler, Joe Perry, Tom Hamilton, Joey Kramer, and Brad Whitford after lineup changes occurred between 1970 and 1971. Joey Kramer suggested the name Aerosmith after hearing Harry Nilsson's album Aerial Ballet which featured jacket art of a circus performer jumping out of a biplane.
Toys in the Attic arrived in 1975 establishing Aerosmith as international stars competing with Led Zeppelin and the Rolling Stones. Rocks came out in 1976 described by music historian Greg Prato as capturing Aerosmith at their most raw and rocking while both albums appear on lists such as Rolling Stones 500 Greatest Albums of All Time.
Joe Perry left Aerosmith following a heated argument backstage at Cleveland Stadium on the 28th of July 1979 during the World Series of Rock festival. Perry formed his own side project known as The Joe Perry Project after taking some of his written music with him.
The band won its first Grammy for Best Rock Performance by a Duo or Group with Vocal for Janie's Got a Gun and achieved their fourth Grammy Award in 1999 for Pink winning Best Rock Performance by a Duo or Group with Vocal category.
Aerosmith retired from touring officially in 2024 though they still occasionally play one-off shows after Steven Tyler suffered vocal injury in 2023 during the third date of their farewell tour failing to recover fully.
