The chart-topping act Lukas Graham comes from which European country?

Lukas Graham is a Danish pop band consisting of lead vocalist and multi-instrumentalist Lukas Forchhammer, bassist Magnus Larsson, and drummer Mark Falgren. The band released their first album, "Lukas Graham", with labels Copenhagen Records and "Then We Take The World" in 2012. The album peaked at number one on the Danish charts.

Their second album "Blue Album" was released in 2015 and earned international attention with singles like "Mama Said" and "7 Years", the latter of which topped the singles charts in many major music markets. The self-titled international debut album was officially released in the United States by Warner Bros. Records on 1 April 2016.

Lukas Graham's music has been described as a pop-soul hybrid. In a review of the band's new album, journalist Jon Pareles of "The New York Times" described their sound as the place "where pop meets R&B". Patrick Ryan of "USA Today" wrote that the band's songs "effortlessly blend elements of hip hop and folk". Lyrically, the songs often deal with relatable experiences like growing up poor ("Mama Said") or drinking ("Drunk in the Morning"). The band's most popular song, "7 Years", describes growing up and aging at specific points in life (from seven years old to 60).
