There are two bands with this name:

1) MK Ultra was an American alternative band that played between 1994 and 1999. The group formed in the Bay Area in the early 90s, and went on to become a hit in local circles. mk Ultra's final album, The Dream is Over, was compared favourably to Radiohead's OK Computer in a Pitchfork review (see review ). MK Ultra was Dan Carr (now in Creeper Lagoon), Matt Torrey(Jets to Brazil), John Tyner and John Vanderslice.

2) MK-ULTRA (also spelled Mk-Ultra, MK Ultra, or Mk Ultra) was a hardcore/thrash band from Chicago, Illinois. They were known for their fast music and outspokenness on political and social topics ranging from capitalism to Christianity. Due to "legal troubles", the band was forced to drop the name "MK-ULTRA" in 1999.[1] They finally broke up in 2000, although the band continued donating songs to compilations for some years afterwards. 2
