There are at least 5 artists named "Kat": 1: Polish heavy / thrash metal band (with very few black metal elements) accused of propagating satanism. Considered as one of bands having most influence on Polish metal music. The band was founded in the end of 1979 by Piotr Luczyk (guitars) and Ireneusz Loth (percussion) in Katowice. Soon next two members - Tomasz Jaguś (bass) and Ryszard Pisarski (guitar) - have joined the band. Kat was playing instrumental hard rock then. In 1981 at Silesian Rock festival they have found a vocalist - it was Roman Kostrzewski. In 1984 Wojciech Mrowiec joined the band and with this team Kat has released its debut "Ostatni Tabor / Noce Szatana". The band made a splendid show at Jarocin Festiwal but then people started to attack the band with accusations about satanism when an other band (Test Fobii - Kreon) have destroyed the cross at their concert and there was a black mass at the cementary not so far. Kat's members casted away these accusations saying they weren't inspirating these acts. Soon Kat went to the tour with Hanoi Rocks and records its first LP - "Metal & Hell" realased in 1986 by Ambush Records. Polish version (with title changed into "666") was released one year later by Klub Płytowy Razem. The sound of the band was quite artificial but the album was accepted by people very well. Shortly after that Wojciech Mrowiec has left the band. Without him Kat played their next two gigs as a support for Metallica in 1987 (it was recorded at video material "38 minutes of life"). The band was also playing before legends like Running Wild, Helloween or Overkill. After releasing the great "Oddech wymarłych światów" album, the band went into a crisis - Luczyk and Loth have left the band for 3 years. Next 2 years after their return the band have released their next album - "Bastard". In 1993 the band's members have recorded their next album - "Ballady" - with a guest performance of Józef Skrzek (keyboard). Piotr Luczyk has left the band forever just after releasing the "Szydercze zwierciadło" album. The band has hold up its activity for the next 3 years after the death if guitarist Jacek Regulski. In 2002 KAT returned and have played as a support for Iron Maiden in the following year. In 2004 the band has split. First they dismissed Ireneusz Loth and shortly after Roman Kostrzewski. New team became - Mariusz Prętkiewicz (percussion), Jaroslaw Gronowski (guitar), Piotr Luczyk (guitar), Krzysztof Oset (bass) and Henry Beck (vocal) - and released the next album, "Mind cannibals". Roman Kostrzewski and Ireneusz Loth started a new band named "Kat & Roman Kostrzewski". 2: A 23-year-old Cuban/Ecuadorian American-born female artist based in Connecticut. Her music styles vary based upon emotional influence and life experience. Her father, Jimmy González, was the front man of a techno-house group called BRAINPROBE and had shows with crowds of over 50,000 people; this is the influence that inspired Kat to become an artist, herself. With completely self-produced music and a born talent for singing, Kat has gained slight recognition through the music sharing website SoundCloud, where she writes: "My name is Katarina. Music and singing have been my passion since I was a little girl and I'm pushing myself to follow my dreams finally after all of these years of wanting to but being too scared. I've been through a lot of trauma and heartache and am still going through hard times; but because of that, I have a lot of stories to tell and this is my way of putting my wounds into art. What differentiates me from others is that my music is from the deepest part of my core and I put everything I have into it. I hope that some of you can relate to it or that it can help you get through difficult times and if not, I wish that it can at least be enjoyed by whomever. It's going to be a long, hard process blossoming into this career but I'll enjoy the journey and lessons learned along the way. At this moment I am using cheap equipment so it's not going to be perfect (especially vocals, so constructive criticism is recommended but along the way I will get better at it! Enjoy." 3: Japan based singer, song writer. 4: A 23 year old Filipino-British singer and vlogger Kat Romero. 5: Kat, or Kat Project, real name Emanuele Cattaneo, is a Italian Hardstyle DJ/Producer who from 2001 released hardstyle music on Wicked Records.
