I have few that are absolutely recognizable by a note or voice: Stepenwolf, The Stones, Boston, Aerosmith, The Guess Who, Beatles (an obvious one), Stix, Kansas, Lynard Skynard, Allman Bros, Doubie Bros., ELP, Eric Clapton, Jimmy Hendrix, SRV, ELO, CSN&/or, Y., Bread, Alice Cooper, Zep, Ozzie, and on and on! Who can you honestly make a beneficiary of this simple subject?
