Due to the high demand and adjustment of dates you have to book the band at least 20 days before the actual event. 

Price depends on size, time and duration of the event as well as on the setting of the sound system, lights and stage. When confirming the event (signing the contract) 30% advance should be paid to assure the booking date. If the organizer cancels the event, the 30% advance belongs to the band. In case of force majeure, when the band cannot assure the event, the advance is refunded to the organizer.
