BrightSide. is a post punk/indie rock  band formed in 2009 in Thessaloniki, Greece. The band ensemble consists of: Konstantinos Skarlatos (lead vocals, guitar), Nestoras Bananis (lead guitar), Miles Lappas (drums and percussion), Thanos Karapantsios (bass guitar) and Nikos Kallianis (keyboards).
The band is influenced by the new wave, post-punk scene alongside its revival through the indie rock bands of the ’00s. Since the spring of 2010, BrightSide. have shared the stage with The Stranglers, Motorama, Soviet Soviet, Get Well Soon, and various Greek bands. They have also performed with other alternative bands at various live stages (Fix Factory of Sound, Stage Volume 1, six d.o.g.s., Block33, Μύλος Club, 8ball, Rover, ΓαιAlive, Silver Dollar, Death Disco) and they have participated in various festivals.
In January 2012, the band’s long-standing idea of creating a festival for greek indie rock/brit pop/alternative/post-punk/indietronica bands took shape. This resulted in the creation of #if (Indie Fest) which has been held with complete success since 2012.
In May 2014 BrightSide. excelled in “Red Bull Bedroom Jam”‘s contest and won an addition to Ejekt Festival’s lineup, which included Kasabian, Editors, White Lies, Darkside and Paul Kalkbrenner. Their performance on Ejekt Festival’s stage received several positive reviews from critics.
BrightSide. released their first studio album in June 2016, entitled “It Begins With A Fall” (Smash Records).
“Things” EP was released as a digital download and as a Limited Edition Cassette (Random Tapes) at Record Store Day 2018.
