n. (laughing hyena English)
Wikipedia
Laughing Hyenas was an American rock band that existed from 1985 to 1995. They formed in Ann Arbor, Michigan. According to Allmusic, "At first, the band specialized in noisy dirges overlaid with the tortuous, throat-shredding vocals of frontman John Brannon. As time passed, their blues connections became more and more explicit." In 1990, Kevin Strickland and Jim Kimball left the Hyenas and teamed up with P.W. Long (Reelfoot) to form Mule. After the departure of the original rhythm section, former Necros members Todd Swalla (drums) and Kevin Ries (bass) joined the band. Ries was later replaced by another Necros bassist Ron Sakowski.
Larissa Strickland (Larissa Stolarchuk) died on October 8, 2006, at the age of 46, from a drug overdose in North Port, Florida.
