Aly and AJ Michalka dropped their updated Song on Dec. 30 - the most appropriate send-off for 2020, wouldn't you say? Of course, what the people really want (read: I'm the people) is a live performance, and oh, did they deliver. For New Year's Eve, the sisters brought their song to the TikTok masses with an exciting virtual gig.

Their video starts with an a cappella rendition of the sisters' song "Slow Dancing" before transitioning into the nostalgic 2007 track. Matching in sparkling suits, Aly and AJ deliver exactly what their grown-up audience wants. They carry the same electric energy from two decades of performing but with mature, sophisticated angst. I expect we'll see even more of these vibes in their upcoming album this year. For now, enjoy the full video above.
