Helene Fischer's self-titled album, released in 2017, was her fourth to sell over a million copies in Germany. She then filled stadiums with an award-winning concert tour, making her one of the world's top-earning entertainers. Fischer, who was born in 1984 in Siberia and grew up in Rhineland-Palatinate, is the biggest star on the German music scene.

Fischer has sold more than 13 million records, mostly in German-speaking countries. "Farbenspiel," with "Atemlos durch die Nacht," was the first album to reach number one on the German charts twice — in 2013 and 2014. It was downloaded over 250,000 times, setting a record for German artists.

Riding the wave of the "Atemlos" hype in 2013, it seemed like the country was full of Fischer fans of all ages and backgrounds. Even the national German football team (in particular, Bastian Schweinsteiger, second from left) was among them. The pop diva performed after the team won the World Cup in 2014 — and the players sang right along with her.

Fischer trained as a musical theater artist, and her live performances are diverse and entertaining. Her mix of "schlager" (folk pop), rock and classical music appeals to many. According to record certifications she has sold at least 15,000,000 albums altogether.

Fischer's 2018 tour has been called "spectacular" and "bombastic." The reason is that the singer has added the troupe 45 Degrees to the program — a branch of the acrobatic theater group Cirque du Soleil. Acrobatics have often been part of her shows, as can be seen from this 2013 performance.

Boyfriend Florian Silbereisen (left) had to do without his Helene while she was on her concert tour. Silbereisen helped launch the singer to fame: She made her first TV appearance in 2005 on his folk music show. Since then, Fischer has appeared countless times on camera and even has her own program. "The Helene Fischer Show" has been broadcast on Christmas Day every year since 2011.

Seventeen Echo Awards and three Bambis are among the countless accolades the singer has collected over the course of her career. But prizes aside, stars know they've really made it when they get their own wax figure at Madame Tussauds. Fischer's statue has been in Berlin since 2011 and its outfit and hairstyle are regularly updated.

Since she emerged as a singer and variety TV star willing to revive a distinctly old-fashioned repertoire of uplifting Schlager ballads, Fischer has sold well over 10 million records in Germany alone. Songs like "Atemlos durch die Nacht" ("Breathless Through the Night") have dominated the charts, and the Russian-born pop princess is no stranger to kitschy TV shows like Schlagercountdown.

Having sold more than 50 million albums since his 1967 solo debut, Heino is a Schlager pioneer known for his trademark dark sunglasses, platinum mop top and rich baritone voice. His smash hits range from "Jenseits des Tales" ("Beyond the Valley") to covers of controversial folk tunes such as "Schwarzbraun ist die Haselnuss" ("Black-brown is the Hazelnut") that were sung by the Hitler Youth.

Jürgen Drews landed a mega hit with "Ein Bett im Kornfeld" ("A bed in a cornfield") in 1976. Today, Germans label the seemingly ageless singer "king of Mallorca" because he has for decades been a staple on the German party scene on the Spanish island. Drews actually started his career playing the banjo in a jazz band.

The 1969 "Mendocino" was Michael Holm's first big hit, and "Tränen lügen nicht" ("Tears don't lie") made it to first place in the charts in 1974. He helped orchestrate a mega Schlager revival in the late 1990s by producing Guildo Horn's hit album "Danke" in 1997.

She won the Eurovision Song Contest in 1980 and came in third twice, in 1970 and 1971 - Katja Ebstein is regarded as the competition's German grande dame. Ebstein's hit song "Wunder gibt es immer wieder" ("There will always be miracles") is an integral part of the German Schlager repertoire. Ebstein also acts in plays, is involved in social projects and politically active.

The Berlin-born singer and composer (and songwriter for Boney M. and others) rose from obscurity in 1965 with his immortal Schlager anthem, "Marmor, Stein, und Eisen bricht" ("Marble Breaks And Iron Bends") — an English version later charted in the US. The boy from working-class Wedding was a rebel who had issues with alcohol, but still released some 260 songs before his death in 2006.

Known for his blonde locks, casual hip swing and beaming smile, Marcus' 1972 release "A New Love is like a New Life" has become one of the best-known songs in Schlager history, a staple of any German record collection. "Music is wonderful because you can capture people's emotions," Marcus once said of the sing-along favorites he performed incessantly until his recent death in May at the age of 69.

Andrea Jürgens was a 10-year-old in 1977 when she sang what would become one of the all-time Schlager classics, "Und dabei liebe ich euch beide" ("And Yet I Love You Both"), which was composed by Schlager hit-maker Jack White. Child star Jürgens would peak young, but returned with a No. 1 in 2010 with "I Only Have a Heart." She died of kidney failure in 2017 after a 40-year career.

Schlager has had its fair share of miscreants and eccentrics who are not afraid to play with the genre's kitschy cliches. With his trademark high-energy hilarity (including climbing all over the stage during his 1998 Eurovision appearance), and gaudy velvet green suit, this Schlager provocateur hit the charts in the 1990s with songs like "I like Steffi Graf" and "Guildo loves you."

Berg was 26 when she went from being a nurse to a Schlager hit-maker with the album "Du bist frei" ("You Are Free") and smash singles like "Schau mir nochmal ins Gesicht" ("Look Me in the Face Again") and "Splitternackt" ("Stark Naked"). A 2001 greatest hits album went five-times platinum, selling 2 million copies. More recently, the singer won the Echo Award for best Schlager singer in 2017.
