Female rock band DX has formed in March 2009 with vocalist Riku, guitarists Nami and Katsumi, bassists Yuki and drummer Kaishi. On 24th June 2009 DX performed at the hall SAREZA in Ostrava the first time. Then the band had a break because holiday was and they were using this time for rehearsal and make new songs. At the beginning of September they had other concerts. Unfortunately, guitarist Katsumi left band in August and from this time DX are only four.
