Biography, Age

The pop singer was born as Sydney Grace Ann Sierota on April 21, 1997, to parents Linda Sierota and Jeffery David. She was born into a musical family as her father is a songwriter and producer while all three of her siblings namely Noah Sierota, Jamie Sierota, and Graham Sierota are also musicians.

Little is known about Sydney Sierota’s early life and educational background but we do know that she began singing from a very early age. She sang for the first time in church when she was only two years old and started playing in a band from the age of five along with her brothers. She once revealed in an interview that she attended high school like every normal child but was home-schooled when Echosmith’s career schedule became tighter.


Sydney Sierota is the lead singer and keyboardist of American alternative pop band Echosmith which she formed originally with her siblings, Jamie (sings and plays the guitar), Graham (plays drums), and Noah (plays bass and sings backup vocals). The band was formed by chance when a neighborhood charity event needed some live music and the Sierota kids got together and played a seemingly random set list, that was the beginning of a structural band that remained relatively unstable until 2009.

Ecosmith released their debut album Talking Dreams in 2013 via Warner Bros. Records. At that time, they weren’t really known in the music world and didn’t have a large fan base. The album featured a hit song Cool Kids which reached number 13 on the Billboard Hot 100 and was certified double platinum by the RIAA. The now popular band’s sophomore album Inside A Dream was released in 2018.

Aside from being the lead singer, Sydney can also play the guitar and keyboard, and all four members of the creative band write their songs, as well as contribute ideas on lyrics and music. Echosmith experienced one of their biggest changes when their oldest brother Jamie left the band in 2016 to focus on his own family after welcoming a new baby. Jamie sings and plays the guitar and was also a co-writer for the first album. His exit was really tough for the band, a decision which caused the rest of the group to lead their songs more with keyboards than with guitars. They eventually got used to his absence and the band has waxed stronger since then.

Echosmith has worked with other artists like Russian-German DJ and musician Zedd in providing the vocals for his song Illusion,  on his second studio album True Colors (2015). Sydney, on the other hand, collaborated with The Goo Goo Dolls on the song, Flood, from their Boxes album. The band which is a huge fan of Coldplay and The Killers did not feature nor collaborate with any other artist for their second album but wrote songs with OneRepublic’s Ryan Tedder and Switchfoot’s Jon Foreman.

Sydney Sierota loves fashion, makeup, and clothes. She had always dreamt of having her own clothing line as a young girl. It is, therefore, no surprise that the rock princess doubles as a model and now has her own clothing line. In May 2015, she was signed by Wilhelmina Models, one of the world’s most prominent talent and model management agencies. For her clothing line, she has also collaborated with iconic brands like Hollister Co, on special partywear collection which includes dresses, tops, and bottoms that are inspired and created by the singer. Prices of pieces in the collection range from $39.95 to $79.95.
