A supergroup sometimes forms as a side project for a single recording project or other ad hoc purposes, with no intention that the group will remain together afterwards. In other instances, the group may become the primary focus of the members' career.
In the early 2000s, supergroups such as Audioslave and Velvet Revolver made their mark. Audioslave was created in 2001, composed of ex-members of Rage Against the Machine and Chris Cornell from Soundgarden. The members of Guns N’ Roses and Scott Weiland from Stone Temple Pilots came together to form Velvet Revolver in 2002. This is a time when supergroups were experiencing a revival; established musicians looked for new platforms to express themselves, as they brought their different genres closer through collaborations that utilized their shared popularity so as to build something fresh and thrilling [10][11]
The very definition of a supergroup hinges on the members already having been "successful". This itself is a subjective term, though metrics such as career earnings, records sold, number of commercial hit songs written and musician longevity can all be used to establish the objective success of a musical band and its individual members.[15][16]
Tyler Golsen in Far Out writes that "Today, the term “supergroup” has something of a negative connotation. It usually signifies a short-term vanity project that attempts to profit off members’ reputations with their past works".[17]
In 1974, a Time magazine article titled "Return of a Supergroup" quipped that the supergroup was a "potent but short-lived rock phenomenon" which was an "amalgam formed by the talented malcontents of other bands". The article acknowledged that groups such as Cream and Blind Faith "played enormous arenas and made megabucks, and sometimes megamusic", with the performances "fueled by dueling egos". However, while this "musical infighting built up the excitement ... it also made breakups inevitable."[18]
