Exitmusic definitely has a good combination of unique, ghostly vocals, backed-up and completed by a good band. I like all of their songs from this live performance and I'm certainly going to "dig" them up; I would like to hear them in a concert.
On the other hand, Active Child has only one song that really impresses me: "Hanging on". This song really haunted me for several days - the first day I heard it I listened to it about 20 times. The harp and the strange voice go along and easily become an obsession. I listened to the rest of their album, but no other song managed to impress me as much as "Hanging on" did.
