Beyoncé and Solange Knowles have both put out strong and influential pieces of art his year-- Beyoncé’s Lemonade was released in April, and Solange's A Seat At the Table in September. While both sisters have enjoyed a great deal of deserved success individually, they can now share a triumph together. The Knowles sisters have become the first sisters ever to have #1 albums on the Billboard 200 chart, let alone the same year.

Beyoncé has had 6 albums sit at the #1 spot, while this is the first (but presumably not last) time for Solange. A Seat At The Table sold 72,000 copies in it’s first week, beating out the anticipated Bon Iver album 22, A Million. Solange began promoting her album just 3 days before it’s release, and has accompanied the album with an E-Book with lyrics and poetry.

Only two (two!) other sibling pairs have ever achieved this high honor: Master P his brother Silkk the Shocker, and Michael Jackson and Janet Jackson. Both Beyoncé’ and Solange have praised and promoted each other's work. "Congrats to my sister on creating this beautiful work of art. I could not be more proud of you @saintrecords. A Seat At The Table is available today!” Beyoncé wrote on Instagram following the album's announcement. Solange spoke to The Fader and praised her older sister, and discussed Beyoncé's themes of activism and black empowerment.  “I'm really proud of my sister and I'm really proud of her record and her work and I've always been. As far as I'm concerned, she's always been an activist from the beginning of her career and she's always been very, very black,” Solange said. “My sister has always been a voice for black people and black empowerment. And I give so much of that credit to my parents.”

Beyoncé and Solange's mother, Tina Lawson, has been posting the most touching proud-mom posts on Instagram.

“How about those Knowles girls. I'm sorry if it seems like I'm bragging, but I just couldn't be more proud right now to see this family history being made, and I also know how hard they work and how much sacrifice they made to do this so they deserve all the Kudos,” Lawson wrote. “I am proud to say that they follow two awesome sibling duos ! Michael and Janet Jackson and Master P and Silk The Shocker. ”

Lawson also compared her daughters to another dynamic sister duo from Houston--Phylicia Rashad and Debbie Allen. “Someone just sent me this. It's Two amazingly talented beautiful sisters from Houston, Texas! Third Ward our hood. Phylicia Allen Rashad and Debbie Allen. These were two of my girl's role models ! Houston Proud. Third ward was a Inner city Black neighborhood filled with pride and lots of professional African americans.”

Congratulations to the two talented and supportive sisters who now share a seat together in Billboard history. Listening to their albums all day is a solid celebration move, right?!
