A comeback teaser photo was uploaded to Taeyang's Instagram today.

Today on Big Bang member Taeyang's Instagram account

A photo teasing a comeback has been uploaded!!

It's been almost three years since you released an album again.

I saw that you posted a photo along with the word "Quintessence" ㅠㅠ

I'm really looking forward to and curious about what concept you'll be coming out with.

All of the Big Bang members' solo songs are good, too.

I'm really looking forward to Taeyang's solo album this time as well.
