Okay, come to think of it, there is at least one group I can think of that I love that might be said to have twee influences, which is current 93
For: Sleighbells, recorders, nursery rhyme singing, songs mentioning kittens, ponies etc., called an album 'All the Pretty Little Horsies', wrote a whole concept album about Noddy, song titles include 'The Ballad of Bobby Sunshine', 'Oh Merry-go-round', 'Happy Birthday', 'A Voice for Catland'.
Against: Tape loops of nazi speeches and people shouting 'JESUS WEPT', white noise, screams, songs mentioning rape, genocide, and the occult, called albums 'SixSixSix: SickSickSick' and 'Lucifer Over London', the concept album was called 'Swastikas for Noddy', song titles include 'Falling Back in Fields of Rape and Smoke', 'Into The Bloody Hole I Go', 'The Inmost Night', 'Twilight Twilight Nihil Nihil' and, in the greatest move ever, 'The Seven Seals Are Revealed At The End Of Time As Seven Bows: The Bloodbow, The Pissbow, The Painbow, The Faminebow, The Deathbow, The Angerbow And The Hohohobow '.
Actually, Current 93 are just fucked up.
