Ever one to keep fans on their feet—she took her time to offer us When I Get Home —GRAMMY winner Solange took to Twitter last night to reveal a new surprise up her sleeve in the form of a performance art piece.

<blockquote class="twitter-tweet"><p lang="en" dir="ltr">So excited to announce “Witness! “ <br>a special performance piece here at the <a href="https://twitter.com/elbphilharmonie?ref_src=twsrc%5Etfw">@elbphilharmonie</a> <br>tickets on sale may 31 <a href="https://t.co/4Py0csJums">pic.twitter.com/4Py0csJums</a></p>&mdash; solange knowles (@solangeknowles) <a href="https://twitter.com/solangeknowles/status/1131715238754230274?ref_src=twsrc%5Etfw">May 24, 2019</a></blockquote><script async src="https://platform.twitter.com/widgets.js" charset="utf-8"></script>

"Witness!," composed and directed by the polymath herself, will debut at the Elbphilharmonie, a stunning state-of-the-art concert hall in Hamburg, Germany on Sept. 17. The venue, which opened in 2017, is home to their very own NDR Elbphilharmonie Orchestra and said to be one of the "most acoustically advanced concert halls in the world."

Other than sharing that tickets go on sale next Fri., May 31, sans url, Solange didn't reveal too many details in the Tweet. The image/event flyer she included in the post offers a glimpse of the beautifully designed interior of the venue with roman numerals across it—perhaps to represent the witnesses of "Witness!" We will have to patiently wait for more info, including if she will be bringing the piece to any other venues or for any other dates.

Her fourth studio album, released on March 1, has been the gift that keeps on giving, thanks the many gorgeous Solange-directed music videos that accompany the tracks. Collectively, the visuals are part of her film, also titled When I Get Home, that she dropped with the album.

Solange has a few other European appearances on deck this year, including as a headliner at Primavera Sound music festival in Barcelona on June 1, as well as their offshoot Portugal fest on June 6. In between her two U.K. dates, at Parklife Festival on June 9 and Lovebox Festival on July 12, she'll make a stop stateside, at Bonnaroo on June 14.
