Elisabeth Rodermund, known as Lisa Middelhauve (born Elisabeth Schaphaus on 28 November 1980) is a German musician, better known as the former lead vocalist and pianist (on the earliest works) of German symphonic metal band Xandria from early 2000, until April 2008, but returned as their singer in 2010, only to finish the remaining live shows due to their second lead vocalist, Kerstin Bischof's departure.

After Xandria, in late 2010, Lisa Middelhauve performed a few shows as guest singer for the French philharmonic metal band Whyzdom.

She also joined Austrian symphonic metal band Serenity[1] for several shows and Delain for their whole 2011 European tour.

But Lisa remained faithful to the piano and wrote songs about failed relationships at the age of 13 years.

[2] However, after replacement singer Kerstin Bischof left the band, she agreed to return for several concerts in spring 2010.
