The 65th Edinburgh military tattoo, which takes place until August 23 in the Scottish capital, is hugely popular.
Tickets for the capital's event have now sold out, but those seeking a taste of what the night has in store are urged to attend Glasgow's free taster session this week.
Thousands are expected to flock to George Square tomorrow, where they will get to watch a host of musicians and pipers at the free hour-long event, which starts at 12.30pm.
The Trinidad and Tobago defence force steel orchestra will perform along with more than 600 others from all over the world, including Highland Dancers from Australia, Massed military bands, an Indian cultural troupe and Massed pipes and drums.
Royal Edinburgh Tattoo chief executive & producer, Brigadier David Allfrey, said the group was "looking forward very much to coming to Glasgow."
He added: "We have a stunning tattoo ready to go.
"We have perhaps the largest gathering of pipes and drums for many years, and an unparalleled number of new contributors from across the Commonwealth, with over 100 highland dancers and a wonderful score.
"And, if this were not enough, we have all three Royal Marine Bands on parade - perhaps the greatest musical instrument on the planet.
"So, it is only proper that we try and share these riches around in this special Homecoming year when Scotland welcomes the world."
Fiona Hyslop, Cabinet Secretary for culture and external affairs, said the event "will showcase the magic of the tattoo, and Scotland's rich culture and heritage to new audiences from across Scotland and those who are visiting us from around the world."
Following the Glasgow show, the group will travel to Dundee and Stirling for further shows.
