The band was formed in 2011 when two brothers (aged 15 and 17), Tomas „Tomo“ Michalcak (lead vocals-guitar) and Lubo Michalcak (drums) recruited another 2 members – guitarist Steven Tomko and bass player Tomas Granec, who was replaced in the summer of 2013 by Paulina Morvay
First performances were held in Clubs in their hometown, Bratislava (SK-Europe), but the following year the band started to make it´s name outside their country. Probably the biggest achievment was a score at the Czecho-Slovak-Polish band competition Radegast Líheň 2013, where ACES were the youngest competitors of 217 bands, but still made it to the 2. place, and had the highest rating of all Czech and Slovak bands. In 2013 the band was playing more gigs in Czech Republic (Ostrava, Opava, Liberec…) but also in Hungary (Budapest) and in Austria (Vienna). In the summer of 2013 they performed at the biggest and most famous Slovak Rock Open-Air TOPFEST alongside names like Iron Maiden or Billy Talent.
