What do you think of indie rock or "alternative rock"?
I like it! It's a nice change from the classic rock I normally listen to! Can you recommend a good group?
I'm a big fan of Green Day. They are an alt rock group. 
I didn't realize they were considered alt rock! I listened to them a lot back in the 90s!  When do you think alt rock got started?
It started with grunge and punk revival bands in the US and UK. Even though those bands became mainstream they still maintained their underground and outsider attitudes. 
That's really interesting!  So I guess a lot of different bands could fit that definition. Is there still a big market for alt rock music?
late 1970s laid the groundwork for alternative music. At times, "alternative" has been used as a catch-all description for music from underground rock artists that receives mainstream recognition, or for any music, whether rock or not, that is seen to be descended from punk rock (including some examples of punk itself, as well as new wave, and post-punk). Although the genre evolved in the late 1970s and 1980s, music anticipating the sound of the genre can be found as early as the 1960s
Huffington Post: "Empires have such a distinct sound I don't know whether to tell you they sound like The National meets [insert alt rock band here] or simply just say it's quality alt/indie-rock blended with subtle 1980s tones. Let's go with the latter."
