The song "Zu Zweit" is a beautiful duet with Cassandra Steen

which wraps itself warmly around the heart like a musical blanket. We can also make good use of it when it's foggy and cold outside and the days are noticeably short. Then the Christmas season is usually not far away and at SEVEN's home his wife's X-mas playlist runs on a continuous loop from mid-November - because the whole family loves Christmas! The singer says: "My favorite Christmas songs are the wistful and melancholic ones that remind you what this time of year is all about. "I'll be home for Christmas" in Whitney Houston's version or "Another lonely Christmas" by Prince are my favorites. I've always wanted to write a wistful yet warming Christmas song and "Zu Zweit" unites that and offers the insight that everything changes only love remains..."

Gospel music is the origin for everything we call soul today and that's probably why Christmas and soul music are so closely linked. Cassandra and SEVEN are both children of soul music and have a lot of common influences. So it's not surprising that Cassandra also loves Christmas and while SEVEN was writing this song, he immediately thought of her and picked up the phone to ask if she would like to write the second verse and sing it right away. Now they sing "Zu Zweit" together.
