I am a big fan of the band Rush.  They are a Canadian rock band with Geddy Lee as the frontman.
I've never heard of Rush! What was their most popular song, maybe I've heard it?
I would say Lock and Key is a favorite.  The critics gave it great reviews, calling it a hit single.
Thanks for the recommendation, I'll definitely look it up! Are they a relatively new band?
Oh my no.  The were formed in 1968, and their most popular line up began in 1974.
Oh, I'm way behind! Who was their lead singer?
Geddy Lee, but my favorite band member is the drummer Neil Peart.  He writes most of the lyrics, which are generally philosophical and deep. 
They sound like a band I would enjoy! Are they still making music together? I'd imagine they're getting up there in years!
They are still rocking!  It is estimated that the have sold over 65 albums worldwide as of 2017
