I listen to metal too. I have never heard of the band Daughter. Are they good?
Theyre amazing, but they are not Heavy Metal
What do you mean not heavy metal? What genre of music are they?
Indie Folk. Its a female lead singer, mellow tones, and amazing lyrics
What's the lead singers name? What are some of their best songs? 
Elena Tonra is the lead singer. No Care is one of thier best songs 
How old are they? Are they a more recent band? I have not heard of them before and I am interested.
Im not sure how long theyve been around but I know the lead singer just put out a solo album. 
Do they have many albums? Maybe I will check them out later on today.
Without searching, I believe they have three albums and one EP. Check them out. I listen to them on Amazon Music and use shuffle
