They quickly gained popularity and played for many years, with 4 recorded studio albums, frequent TV appearances and constant live touring.
So they took it even further, doubled the line up with 3-piece brass section and mixed up their older sounds with ska punk and some Ukrainian folk.
The line up was doubled with the powerful brass section (trumpet, trombone, saxophone) and the music drifted in the direction of ska with a touch of swing and Ukrainian folk.
That show brought the band to 9 more big open air stages in the next few months, with the audience varied from 5,000 to 100,000 (Day of Youth on the main Kiev's square, Maidan Nezalezhnosti).
In September 2004 the band was invited to take part in Djuice-Drive tour (sport palaces in the 6 biggest cities of Ukraine).
Beyond Europe, Mad Heads XL have performed at Ukrainian festivals in Toronto, Ontario, Canada in 2010, and Dauphin, Manitoba, in 2011.
Commanding a strong fan base in the Ukrainian-Canadian community, they returned to Toronto again in January 2012 performing material from their new album УкраїнSKA and "Royal Malanka".
For both events, Mad Heads XL were joined onstage by Ukrainian violinist Vasyl Popadiuk (aka "Papa Duke").
