What artists had a successful solo career while being in a successful band?

This has always intrigued me a lot... well there are plenty of artists who had successful solo careers after leaving a band, it's always super cool and interesting when they have successful solo careers while being in a band or group. The main person I think of is Gwen Stafani. Her first solo hit while being in No Doubt was the forgotten and underrated song "South Side" with Moby which was a top 15 hit in 2001. She then went on to have a couple big hits with Eve, including the #2 smash "Let Me Blow Ya Mind". While No Doubt technically was on hiatus, they weren't broken up and still putting out stuff and had some successful songs from 01-03. Anyways, who else can you think of? And I don't just mean rock, I mean all genres including hip hop, country, and Kpop.
