I love the song Radioactive by the Imagine Dragons.
They are a great band, They formed out in  Las Vegas, Nevada,
I never knew that. What year did the Imagine Dragons form?
Im not sure about a exact year but the studio album "Night Visions"  came out in (2012), 
Oh cool. That was a really good album.
"Billboard" placed them at the top of their "Year In Rock" rankings for 2013 and 2017. So they are still making music today.
Thats cool! I havent heard any of their newer music.
Well some magazines have called them the  Biggest Band of 2017
Oh wow! I didn't think they were still that popular.
"Rolling Stone" named their single "Radioactive" the biggest hit of the year on 2017
