Usually tickets for the festival, held every five years, are in very high demand with people often not being able to obtain them, despite standing in line for hours and frantically monitoring the ticket sales website.
People outside Latvia will be able to buy their passes at www.bilesuparadize.lv.
The venues for the 2018 festival will have greatly increased capacity, with the Daugava Stadium adding 5,000 seats and the Mežaparks open-air stage a further 8,000 to bring its capacity to a whopping 30,000.
Tickets will cost from €2 to €65 and people will be able to buy just four in a single session. The €65 ones are for the best seats in the two special performances.
Children up to the age of seven, if they'll be sharing a seat with their guardians, will be able to attend for free. Participants will likewise be allowed to enter the closing concert for free.
The 26th Song and Dance Festival coincides with Latvia's founding centenary, and it is expected to be a massive gathering that celebrates Latvia and its choral and dance tradition, with 63 separate events slated to take place.
The Song and Dance Festival has been held since 1873.
