After learning to play guitar Mark formed his first band 'Gekko' at the young age of 15.  Gekko went on to become one of the best, most accomplished local bands over the next few years playing shows at some great venues/festivals including Dublin Castle, Bulldog Bash and Rock In The Park as well as performances on local BBC Introducing shows.  When the band split in later years Mark continued to play as frontman of 'The Marksman' acoustic duo with percussionist Clint Henderson. In January 2013 he decided to pursue his dream of his originals career as a soloist under management and started performing solo as Mark Sullivan.

With the solo career starting well and his fanbase growing Mark Sullivan is a well accomplished singer/songwriter from Hitchin, Hertfordshire with a
massive voice and an ear for writing memorable and immediately familiar sounding songs.

Mark has crafted his art on the road with hundreds of shows that include all the expected stages for such a troubadour plus incredible experiences such as opening at Wembley Arena, performing at The Houses Of Parliament, the US ambassadors private London residence and receiving an award from Rick Wakeman.

Mark was starting to play some good venues and getting booked around London a lot more, playing shows at venues such as the 12 Bar Club, Alleycat Bar and Proud, Camden.   In August 2014 Mark was booked to perform at Osfest, a growing festival which now boasted a 10.000 attendance which marked the first stepping stone to bigger things. With London shows now a weekly thing Mark was getting booked for special events such as venue launch nights in the city.  Off the back of the performance at Osfest the start of 2015 Mark was booked to play a show at The Troubadour, London which in turn secured him a small UK tour with London based music agency Live and Loud. This made way the chance to play at some great venues around the country including Elland Road Stadium, Ricoh Arena, Bolton Arena and Wembley Arena through the start of 2015.  Whilst on tour we received confirmation Mark had been selected as a finalist for Government backed 'Rock The House' which was a scheme aimed at finding the best emerging musicians the UK had to offer. Mark performed and won soloist category at The Bedford, London and went on to play at the Houses Of Parliament Guest Rooms, followed a few months later with an exclusive VIP show at the US Ambassadors residence at Winfield House, London.

This raised Mark's profile higher again and went on in the second half of 2015 to play shows at The Water Rats, Ronnie Scotts, The Bedford, Farr Festival, Marylebone Summer Festival, Rhythms Of The World and also supporting artist Kelvin Jones several times at shows.  At the end of 2015 Mark was booked to play a new night at London's 02 Brooklyn Bowl, 'New Blood' which again highlighted the very best emerging musicians on the scene.

Starting 2016 strong he was being booked at some top venues including, The Garage, The Hard
Rock Cafe and Century Club, Soho.  With his career now progressing it was time to start recording some new music and after speaking with several top producers, Mark flew out to America (NJ) to record the next EP with grammy nominated producer Steve Greenwell, and was lucky enough to have some great session players feature on the tracks including Jack Daley on bass.  On return from America and the new tracks being prepared for release Mark was invited to London TV to talk about his music and blossoming career which then led to a slot at the first Major festival, Isle Of Wight 2016. After this, booking agency Coallition Talent booked Mark for the well recognised Coffee House Sessions tour around London and were so impressed they booked Mark for two festivals following this, The Big Feastival (20,000) and Camper Calling (6,000).  With a good number of 2017 festivals lined up including Cornbury Festival, Meraki Festival, Camper Calling, Herts Pride Festival and The Big Feastival another great year is ahead. Mark has also recently supported July Jones at Notting Hill Arts Club and has now been added to Inspired Artist Agency’s roster with a tour lined up for October 17’ with UK, Nashville and Ireland based artists.

Invited to Bucks New Uni to play a Live session for BBC Introducing where he played a 3 track set, now out on BBC socials and the last single from his third EP receiving excellent reviews his online following with Spotify increased dramatically into 2018.


2018 saw Mark release another brand new single in February as he headed of on another UK tour to promote the release.  At the later part of 2018 Mark released another single with the full band which built up to a headline show at London’s 229 with support from Georgia and The Vintage Youth marking a new direction in his music.  His latest single release for 2019 'Wasting Time' has shown the sound of the band on record with more tracks on the way,  Mark enjoying releasing a constant stream of music with Spotify streams now close to 150,000 in the last 6 months.
