The forth-coming Transgressive Roadshows have been pulled after the split of one of the main acts Larrikin Love.
A statement says: "Despite our best efforts to convince them, there was unfortunately no way we could convince Larrikin Love to make these their last remaining, farewell shows... We wish them all the best in their independent futures...
"It was decided that, with their absence from the bill, and no suitable replacement available with such short notice, the show wouldn't be quite the same."
The date at The Great Escape in Brighton on May 18 featuring Foals, Battle and Mechanical Bridge is unaffected.
The rest of the shows are to be rescheduled for later in the year.
Refunds are available from point of sale.
The cancelled dates this May are:
Wed 9, Glasgow Arches.
Thu 10, Birmingham Custard Factory.
Fri 11, Liverpool Academy.
Sat 12, Bristol Anson Rooms.
