This was the category I most looked forward to because I also have a penchant for female fronted rock. This is also the only category I did some research for and submitted something that wasn’t already in my collection. I didn’t want to submit something obvious like Halestorm and I thought metal bands like Epica were off-limits because you said:
Overall the bands I found were quite disappointing but Grace Potter stuck out to me. I haven’t yet had the time to work my way through their catalogue but will do that later.
