Hugo Keenan's only prior appearance at Thomond Park was in an Ireland under-20s trial game over three years ago.
"But the stadium was empty that day and I think it's a sell-out this week so it will be different, yeah," smiled the 23-year-old.
A veteran of Ireland's under-20 World Cup final loss in December 2016, Keenan gets his big chance at full-back for Leinster in Limerick this evening.
Jordan Larmour and Rob Kearney have been given the night off as Leo Cullen rings the changes - 10 in all from last week's crazy eight-try win over Ulster, while Munster have made seven, with Joey Carbery returning on the bench.
And so Keenan - a former Leinster Senior Cup winner with Blackrock alongside Carbery - will experience that special Thomond welcome.
"It will be a tough one," he admitted. "The lads have been telling me that playing down in Thomond is such a hard place to go, the crowd is always quite loud and hostile.
"It probably gets you for the first bit, but it's just like any other game, you can't let the crowd effect you or have any influence on you or else it will affect your performance.
"You just have to ignore it and get on with it and I find that once you get on with the game then everything else just doesn't really matter.
"You are just so focused on the game, you ignore the crowd and don’t really listen to them."
Keenan has experience of cauldron-like stadiums, having faced France in one in the under-20s Six Nations.
"Jesus, that was mad hostile," he recalled.
A big Chelsea fan, soccer was Keenan's first love - ex-Shamrock Rovers and Shelbourne defender Keith Dignam is his uncle - and he played with Mount Merrion until he was 17.
But rugby won out as he blossomed late at Schools level.
He has also played out-half for Ireland's Sevens team, crediting that exposure with readying him for PRO14 rugby.
His breakthrough actually came last Christmas, but a broken collarbone against Connacht ended his season. This will be his sixth start in seven appearances this term.
"Obviously it was good to get a good run while the guys were away at the World Cup," he said.
"I got a few starts there and last season I had a good few injuries so staying injury-free is a big one for me so, touch wood, hopefully that can continue.
"And hopefully just get a few more shots and keep putting my hand up, and put as much pressure on Jordan and Rob as I can".
