Toys In The Attic  by Aerosmith

In 1975, from January to March, Aerosmith were at the Record Plant Studio in New York recording their third album. The album would be named Toys In The Attic and released in April 1975. Joe Perry's initial intention was to name it Rocks. That title was eventually kept for the band's next album. The album's producer was Jack Douglas, with whom Aerosmith had started collaborating the previous year, and this would continue for their albums in the 1970s.

Toys In The Attic is the album with which the band from Boston built its legend in the United States. Songs like Sweet Emotion and Walk This Way became some of Aerosmith's most defining and characteristic tracks. Specifically, Walk This Way was destined to become a landmark song eleven years later, when it was re-recorded with Run D.M.C., building a first bridge between Hard Rock and Hip-Hop. The difference with the two previous albums was that Aerosmith wrote the songs for the album from scratch, as the other two albums consisted of songs they already had ready before needing to record them, songs they performed in various clubs before entering a studio.

The album managed to sell 9,000,000 copies in the U.S. Toys In The Attic remained on the Billboard charts until 1977 (!)
