Rather than a person, Lucas Graham is a Danish band fronted by Lukas Forchhammer, a Copenhagen Boys Choir alumnus whose horizons were broadened, as the story goes, by Dr. Dre’s album 2001. After working the proper European channels, the group’s hit “Drunk In the Morning” helped secure an American deal with Warner Bros., which in turn released their eponymous LP in late 2015. It wasn’t long before a hit single, the piano-tinged, autobiographical “7 Years,” climbed to No. 2 on the Billboard Hot 100. An even more accurate reflection of its popularity might be the 225 million Spotify streams it received in just one month (March 2016), more than enough to send these burgeoning pop stars spinning down the promotional chute. Mariah Carey stole all the headlines, but Lukas Graham also appeared on Dick Clark's Rockin' New Year's Eve last month, celebrating their two Grammy nominations for “7 Years” out of three overall.
