This amateur 2010-ish shitty cell phone vid is still a fav of mine. IIRC this was when Fergie had her solo album with some corporate pop tunes on it that I didn’t care for. Then when I saw her in this vid nailing Ann Wilson’s parts (one of my favorite email vocal rock performances is Heart Barracuda), filled up and channeling her inner Mick Jagger with the chicken strut, just awesome on every level. Despite the glam, it’s her spot on hitting of the high registers live that is so impressive and completely shocked me when I first saw it
