One of my favorite bands is Rancid, the American punk rock band formed in 1991.
I've never heard of that band, do they still make music now?
They do but have different band members now. Rancid has released 9 studio albums.
Have they won any music awards like a Grammy?
No they haven't. Many people consider Rancid, along with Green Day and the Offspring, the reason punk went mainstream.
I have heard of Green Day before, but I don't know that I would recognize any of their music.  Does punk have a big following these days?
They do. Punk typically has a fast paced song with hard-edged melodies and singing styles.
