Rea Garvey is such an amazing artist, I can totaly recommend his music ( He is very underrated)

Look up Germany The Voice 10 yr anniversary Coaches sing When I Ruled The World. Best by far !!

Helene might be the biggest star we in Germany have ever had and still outside her obviously big fanbase she is criminally underrated. This duet here was as the title says from her own show from 2015. Something quite similar could be her duet from her 2017 show with Celine Tam and You raise me up or you could listen to some of her German music. That's after all her bread and butter so to say. Oh and something. Helene sang this song on her own the same year in Vienna's famous Hofburg. Because you said that she was in this song better than Rea. There is a video of it on her channel as well if it is available from the US.

Reeeeeaaaa

I think if you listen to her version of Halleluja, when she sings on her own, you will love it. If you want try "Never Enough" from the Helene Fischer Show, thats also one of may great and stunning performances of her. ❤ Rea Garvey is also a great singer with many good songs.
