BETO KUPPER hails from Sao Paulo - Brazil and his music career began at the age of 10 when he started playing piano. At the age of 15 he discovered the bass guitar and hasn't put it down since. He is a seasoned performer and has gigged with many bands in both Brazil and Ireland. His ability to play both bass guitar and sing is matched only by his love of the music he is playing citing Thin Lizzy, Deep Purple, Black Sabbath, Led Zeppelin and Kiss as his most influential bands. He founded Mata Hari in 2001 in his hometown and enjoyed lots of success there playing hundreds of gigs but late 2005 he decided to move to Ireland and seek out other players to take Mata Hari to the masses.

JOHNNY ROZ was born in Bratislava, Slovakia and comes from a musical family (his father is a pro drummer). He first sat behind the kit at age 14 and has been in bands ever since. He was in his first professional band, Vanilla Club, when he was 20. The band released one album, one video and had many support tours. However, in 2003, he joined one of Slovakia's biggest punk rock bands - Ine Kafe. He released another studio album with this band, 4 official videos (myspace.com/inekafe), 3 Slovak and Czech tours, over 400 gigs in 3 years and the honour of playing at Woodstock to a crowd of 450,000 people. After the band's break up he moved to Ireland to play music and has become the rhythm master for Mata Hari.

COLM makes up the "exotic" third of the band, born and reared in Cork, Ireland. Like the rest of the band his music life started at young age when he was 14. Then, after finishing school, he got accepted to the Rock School in Ballyfermot and graduated with honours in 2003. His virtuoso ability has left audiences both in awe and inspired. Whilst in the Rock School he was a member a of an original band "Made in Taiwan", who had many headlining performances in Whelans, Eamon Dorans, Voodoo Lounge and Temple Bar Music Centre and also recieved interest from Warner Bros with talks of deal. Unfortunately, the band split due to personal differences and Pat joined many different professional bands all over Ireland and has played everything from jazz to country and blues to rock and metal. He joined Mata Hari to play the music he wanted to play in th places where people want to hear it.
