Sombr has sparked fresh festival buzz after teasing a special guest at Coachella ahead of his performances on both Saturdays, April 11 and April 18. The 20-year-old musician shared the message on Instagram, immediately fueling fan speculation about who might join him on stage.
In an Instagram Story posted on Saturday, April 11, Sombr wrote, “Don’t miss this new song & special guest.” He did not name the guest, but the post quickly set off debate online.
Fans quickly floated two major names: Taylor Swift and Olivia Rodrigo. Many believed Swift could appear, especially as some online users pointed to her growing friendship with Sombr.
The excitement, with fans posting reactions such as “surely it has to be Taylor” and calling the possibility one of the biggest potential Coachella moments.
Taylor Swift and Olivia Rodrigo Lead the Speculation
Not everyone agreed that Swift was the most likely choice. Some fans argued that if she did not appear during Sabrina Carpenter’s set, she would be unlikely to join Sombr on stage instead.
Others connected Sombr’s post to Olivia Rodrigo. They noted that he shared a Joy Division song in his Story, which some interpreted as a clue because Rodrigo has cited the band as one of her biggest musical inspirations.
The intrigue comes not only from the mystery guest, but also from the timing. Sombr is already set to perform at one of the year’s biggest music festivals, and his teaser added another layer of anticipation just before he takes the stage.
The mention of a new song also gave fans more reason to pay attention. That combination of unreleased music and a possible surprise appearance turned a short Instagram Story into a major talking point.
