Sienna Spiro ends her 2027 tour in Dublin ten days before Glastonbury

Sienna Spiro’s official tour page lists Fairview Park, Dublin on 15 June 2027, and MCD describes the Dublin show as the conclusion of her My House Tour. Glastonbury begins ten days later on 25 June, with no currently announced dates across the festival weekend. This is meaningful nearby UK/Ireland summer routing context, but not a tightly bracketed Glasto shaped hole or evidence of a booking.
