Seele mit Herz (English: Soul with Heart) is the debut solo album by German singer Cassandra Steen. It was released by 3p on 4 August 2003 in German-speaking Europe. Recorded within a hiatus of her former group Glashaus, Steen worked with producers JC-Mjusix, Nachtwandler, Nene, and Thomas Ruffner on the bulk of the album that combined rhythm and blues with soul pop music. Label mates Moses Pelham and Illmatic as well as rappers Eko Fresh, Azad and Kool Savas appear as guest vocalist on the album.
laut.de editor Alexander Engelen rated the album three out of five stars. He found that "even though Cassandra's voice clearly dominates the album, the sometimes sad, sometimes amorous lyrics and the calm, sensitive music create a fitting unity. You won't find any dance hits, upcheering tracks or classics on Seele mit Herz. But for a successful romantic evening it is enough that Cassandra Steen takes the listener on a journey through her heart and soul."[1]
