Oh geez. Recommendations? That's so difficult because I love so many BA songs. The entire CexCells album is absolutely perfect. My favorites on there are: "Snuff on Digital", "Bitter for Sweet', 'Semiotic Love', 'Cities of Night', 'Wake up, Open the Door, and Escape to the Sea'. Also, some bonus tracks that were great: 'Mute', 'Blaqk Electric', 'Boys and Girls'.
On Bright Black Heaven, I love 'Faith Healer', 'Deconstructing Gods', 'With Your Arms Around You', 'Bliss', and 'The Witness'.
Their most recent album, Material, I'm still getting used to, to be honest. It's a very different sound from the last two albums generally speaking. But 'First to Love' is amazing, 'Anointed', and 'Ceremonial (Burst Into Stars)'.
Another bonus song I really like that's actually a cover: 'You Spin Me 'Round (Like A Record)'
Oh, and don't forget to listen to their new song from the upcoming album. 'The Viles'. It's fucking spectacular.
