This newly formed music genre is based on rock music featured in a limited play list of songs ranging from late 1960’s through today with more emphasis on the earlier hits by artists associated with the "classic rock era". It is often referred to as a specific genre of music by casual fans of those bands. British rock bands make up a central pillar of classic rock artists; significant among these are The Beatles, Led Zeppelin, Deep Purple, The Kinks, The Rolling Stones, The Who, Jethro Tull, Pink Floyd, and Cream. Many different songs from these acts are likely to appear on the play lists of classic rock radio stations. Certain American rock artists are also classic rock legends, including Aerosmith, The Doors, The Eagles, Steve Miller Band, Jimi Hendrix, and Credence Clearwater Revival. Arena Rock bands such as Styx, Boston, Journey, REO Speedwagon and Supertramp also often appear on classic rock lists. In many areas, Southern rock, notably that of Lynyrd Skynyrd, 38 Special, and the Allman Brothers Band forms a significant subset of classic rock play lists as well. Many other bands may appear occasionally on classic rock stations, but only limited to a few familiar songs. For example, while the band Steppenwolf recorded over a dozen studio albums, only two of their songs “Born to be Wild” and "Magic Carpet Ride” are likely to be heard within the classic rock format. The 1970s works of singer-songwriters like Billy Joel, Jackson Browne, and Elton John are popular within the classic rock format; their later works are usually not. Much of the 80s and 90s output of rock veterans such as U2, Tom Petty, John Mellencamp, and Bruce Springsteen is also incorporated into the format. This is possibly the genre most recognized by the average listener. Here you have songs from musicians who produce a wide range of music, but fit into a genre that’s unmistakably a ‘classic’.
