Astrid S

Growing up in Berkåk, a tiny village in Rennebu Municipality, Smeplass played piano at home and flute in her school's marching band. However, she felt classical music was too confining, so she learned guitar and began writing her own songs, inspired by her main influence, John Mayer.^[2] At age 13, she learned to speak English.^[3]

Smeplass released her first single "Shattered", which was co-written by American singer-songwriter Melanie Fontana, after participating in Idol - Jakten på en superstjerne in 2013; she was 16. She signed a publishing deal with Sony ATV Music Publishing shortly afterwards. Her first single with her new artist image, "2AM", was released through Universal Music in 2014, releasing in the U.S. in 2015.

She also released a cover of the single "FourFiveSeconds" by Rihanna, Kanye West, and Paul McCartney.
