The American ambient pop band from El Paso, Texas are already playing Irish dates this month in Limelight 2 Belfast and The Academy.
Cigarettes After Sex rose to fame through music recommendations on YouTube, which led to live performances across Europe, Asia, and the US.
The band released their self-titled debut studio album on June 9, 2017.
Their best known track Nothing's Gonna Hurt You Baby also featured this year on the series The Handmaid's Tale.
Bloggers have been raving about the four piece's talent for years, such as Jae Pyl of Independentmusicnews.com who commented that "there’s just such an intimacy to Cigarettes After Sex's sound that it’s impossible to not let it into the pit of your belly".
Tickets for the band's Olympia gig in May go on sale this Friday.
Their November dates are for sale here
