The following year, the band released their next album, "A Night in the Ruts" ("Band-Aerosmith Bio", N/A), which bombed. After this disappointment they waited until October 3, 1980 before releasing their "Greatest Hits" collection, which remains their best selling album with over 10 million copies sold ("Inductees", N/A). Also in 1980, Jimmy Crespo became a member of the band, but soon afterward, Brad Whitford left to also start a solo career ("Aerosmith", N/A). The next year, Rick Dufay was chosen as a replacement ("Aerosmith", N/A) and the band continued their mission to rock the world. Another year passed and yet another album, "Rock in a Hard Place", was released ("Band-Aerosmith Bio", N/A). The album flunked. It was becoming obvious that the newly formed Aerosmith was not going to work out.
In 1984, ex-guitarists Joe Perry and Brad Whitford attended an Aerosmith show in Boston, and soon afterwards the old band was put back together ("Inductees", N/A). In 1985, Steven Tyler and Joe Perry completed a drug rehabilitation program. Now completely on their feet, the re-formed Aerosmith released "Done With Mirrors" on November 3, 1985 ("Band-Aerosmith Bio", N/A). The following year, the band released an album they called "Classics (live)" ("Band-Aerosmith Bio", N/A). With all the albums they had already released, it was about time they were noticed by another group. This happened that same year when rappers Run DMC approached them about their song "Walk This Way" from the album, "Toys in the Attic"("Aerosmith Biography", N/A). The rockers and the rappers came together to remake the song ("Aerosmith Biography", N/A). On September 27, 1986, the new "Walk This Way" hit number four on the charts. Until they could put together an all new album, the band released a second "Classics (live)" ("Band-Aerosmith Bio", N/A), based on the success of the first one. The following year, they came out with another new album, "Permanent Vacation" ("Band-Aerosmith Bio", N/A).
