I have not done this but I think it should be
has_one :artist_event # to match ArtistEvent belongs_to event
has_one :artist through: artist_event # note, singular artist_event

However, in this scenario I don't think you need the join table at
all, why not just have
Artist has_many events
Event belongs_to artist
