The band describes their music genre as heart rock,[1] a name given to their style due to the emotional, heartfelt content and message of their songs.
During the years SEVI captured the public attention with their original and recognizable style, the powerful female vocals and melodic songs and lined up among some of the most successful rock and metal bands in Bulgaria.
Their music was highly appreciated by famous artists like Johnny Gioeli (Axel Rudi Pell), Thomas Vikstrom (Therion), Jen Majura (Evanescence), Luca Princiotta (Doro Pesch), who also participated in collaborations with SEVI in their albums.
Not only that but SEVI were invited to open the shows of the big stars like Europe, Black Stone Cherry, Tom Keifer, Hollywood Vampires and Evanescence in Sofia.
In 2005 Svetlana "Sevi" Bliznakova is invited by Italian record producer Rocco Milano to take part in a CD compilation with the song “On My Own, which she had co-written with Pino Biaggioli.
Svetlana is (as of 2016) the only Bulgarian singer to have performed in the show of Sky Italia in "Club Lost" during the Sanremo Music Festival in 2007.
In January 2010, she solidifies the idea to create a wider platform and develop her career and claiming a stake in the music business.
In August 2010 the two guitar players leave to be replaced by the former guitarist of Bulgarian alternative rock band "Awake" – Peter Bratanov.
[14] "Can't Stand the Pain" and SEVI are named "Band of the week" by Rock Symphony Radio in Lima (Peru).
[16] Later in the same year, on the precise date of November 11, 2011 (11 / 11 / 11), SEVI release their second single and accompanying video to their song "Limited Edition".
The first one is created for the "What Lies Beyond Tour 2012" and it presents the band as pirates (in full regalia, replete with functioning cannon), scouring the world's stages gathering new fans by the thousands.
The stage is set with an old-style gas pumping station, like one would see while crossing the border between New Mexico and Nevada; the guitarist lighting a cigarette dangerously close to the pump; the keyboard player in dirty overalls as a mechanic who's ready to take a quick peek under the hood; and the rest – a small team of desperados, ready to set up camp anywhere and entertain the locals.
Along the way, while developing these shows and promotions, SEVI start to compile ideas for their second studio album, teasing audiences with the occasional live preview of a new track.
On March 23, 2013, SEVI opens the bike riding season in Sofia, with a performance on a moving flatbed truck platform, while being followed by a motorcade of avid riders.
The beginning of 2014 signals yet another lineup change where keyboard player Tania Apostolova is replaced by Dessy Markova – an experienced keyboardist, who has worked mainly with cover bands, cruise musicians, and is a rockin' music pedagogue.
The stage was set to look like the aftermath of a battlefield, the musicians (including two guest backing vocalists) dressed in black, covered in a cloud of haze.
The show starts with a soundscape of brutal winds, clinging swords (courtesy of Rally Velinov), and it features the vocal talents of prominent Bulgarian actor, Asen Blatechki, who reads out lines from the album's eponymous track: "It never ends...so stand... and prepare yourselves...'cause the battle...never...ever...ends" cuing the band to blast into the opening riff of the song!
On 11 September SEVI opened the show of Evanescence in Arena Armeec and performed their single "To Hell and Back" along with Jen Majura.
After the album release, SEVI film the video of “To Hell and Back” – the featuring track with Jen Majura of Evanescence.
In November 2020, vocalist Svetlana Bliznakova releases her debut solo album Tomorrow – acoustic rock featuring another duet with Johnny Gioeli called "Jaded".
The band worked on the track with the world-famous producer and songwriter Kane Churko, whose name stands along with the projects of some rock giants like Five Finger Death Punch, Ozzy Osbourne, Halestorm and more.
SEVI's first such concept, the so-called Pirate Show, was developed in order to enhance the audience's experience for the promotional release of What Lies Beyond, the band's debut.
Coupled with the video presentation of the song “The Victim", SEVI set an intimate stage/scene inviting folks to hear and enjoy the band's softer side.
The stage is decorated like a cozy and familiar room, hats and umbrellas hanging on hooks, candles shining a soft light on Svetlana's silhouette, and a chandelier similar to the one used on the video for "Victim."
One of SEVI's most notable shows – "Last Call for 2013" – finds Svetlana in a Steampunk top hat with goggles, leather gloves and chains, with a large metal plate fashioned into the band's logo which adorns her microphone stand.
When it came time to present “On My Own", one of the first songs to be featured on SEVI's second release – The Battle Never Ends, the stage is decorated to resemble a train station, with the musicians acting out bits and scenes from the music video to the delight of fans.
