Envy of None is sort of a supergroup. Three members, guitarist Alex Lifeson (Rush), bassist and backing vocalist Andy Curran (Coney Hatch), and keyboard and guitarist Alf Annibalini are music industry vets with probably over a century of experience among them. Lifeson alone has been around for over 50 years.
However, Maiah Wynne the singer-songwriter fronting the band is only 28 with maybe a decade of experience. She's a solid singer and songwriter though, holding her own with the three veterans, every one of them old enough to be her father or even grandfather. Oddly, the band doesn't have a fixed drummer, using various drummers from the Canadian music scene as session players.
Cute note: not only is Lifeson in the band with Wynne, but he plays on some of her solo work, too.
