PeR

PeR (Please Explain the Rhythm) is a Latvian pop and beatboxing band formed in 2007. The original line-up was Ralfs Eilands, Emīls Vegners, and Pēteris Upenieks. Vegners left the band in 2007 and was replaced by Edmunds Rasmanis. But when Upelnieks left the trio in 2011, he was not replaced, rendering the band a duo consisting of just Eilands and Rasmanis. After three failed attempts in earlier years to represent Latvia in the Eurovision Song Contest, PeR won the 2013 Dziesma contest and represented the country in the 2013 Contest with the song "Here We Go" and placed last in the second semi-final.

Early years (2007–2008)
The band was founded in 2007, with original members; Ralfs Eilands, Emīls Vegners, and Pēteris Upelnieks.

After the festival, the band travelled to Moscow, Russia, to compete with other artists on the talent show Minuta Slavy (Minute of Fame), with the band coming in fourth place during voting. The band returned to Latvia where they received an invitation to participate in the annual music event Bildes 2007. This was the last event with the original members.

In 2008, Emīls Vegners left the band and was replaced by Edmunds Rasmanis. The band gained popularity appearing on the first series of the Latvian television station LNT contest Latvijas zelta talanti, the group managed to reach the final, but failed to win.
