Speaking of music I enjoyed (and the first interaction with an NPC that I actually really liked) was the Tiefling Bard Alfira
I've heard Larian really wants people to play the bad/evil side and really test it out in EA because they said most people tend to go good in their games. Sadly it seems to put out tons of interactions/characters I just don't like. It was really a nice breath of fresh air to have that NPC interaction.
