She was always solo. Seriously, are any of the original members even left? I don't get why these female fronted bands (Paramore, Versa, Etc.) go through male members so quickly. Maybe there's some dating going on, and once they break up the dudes get kicked from the band
Don't forget Evanescence.
But honestly...I like this cover. I hope she writes songs of this caliber. I may yet like Cassadee Pope, even though I don't like Hey Monday.
