BBCOasis fans have poured into Murrayfield Stadium ahead of the band’s opening show of their three-night Edinburgh run.
Crowds donning bucket hats and official T-shirts queued to secure a prime viewpoint before the band takes to the stage at about 20:15.
It marks the first time Liam and Noel Gallagher have performed together in Scotland since the band split in 2009.
About 70,000 people are expected to attend Friday’s concert, with similar crowds expected for the reunion gigs on Saturday and Tuesday.
The shows come during Edinburgh’s festival season, when the population of the city almost doubles during the month of August.
Some hardcore fans braved blustery conditions outside the national rugby stadium on Friday afternoon to hear the band run through their soundcheck – hours before doors opened at 17:00.
An Oasis store which opened on George Street on Monday has already welcomed thousands of customers, some spending hundreds of pounds on official merchandise.
It is estimated the concerts could provide the local economy with a boost of up to £130m.
On Thursday evening, a giant drone display of the band’s logo appeared in the skies over the stadium.
Murrayfield was the site of Oasis’s last Scottish concert on 17 June 2009 – mere months before they split at the Rock en Seine festival in Paris.
Support comes from 90s indie stars Cast and former Verve frontman Richard Ashcroft.
A short walk from the stadium at Murrayfield Ice Rink, Scotland’s top Gallagher tribute act Definitely Oasis warmed up the early crowd.
Their lead singer, Brian McGhee, said the band had never been busier since the group reformed.
“We’re always busy, but this is probably the busiest year we’ve had,” he said.
“Next year is looking like being even busier. The demand has just gone insane, it has just gone through the roof.”
His bandmate, Noel Gallagher alter-ego Martin Reid, said it was easy to see why tickets for the gigs had been like gold dust.
“Noel’s songs have just stood the test of time,” he said.
“The thing is, it doesn’t matter what you think of the band in terms of the attitude, the songs are just phenomenal.”
The crowd could exceed the record set last year by Taylor Swift for the largest stadium concert in Scottish history.
ScotRail has put on late-night services on top of an already enhanced festival timetable for those travelling from elsewhere in Scotland.
Additional trains to Glasgow Queen Street, Dundee, Perth and Dunblane will leave from Haymarket, about a 15-minute walk from Murrayfield, after the gigs.
