Irukandji can refer to three bands. 1. Irukandji is a female fronted progressive metal/hard rock band from Norwich, England formed in 2007 under the name Strength of Presence, (initially as a semi-acoustic trio of two guitars and lead female vocals). In 2008 they recruited a drummer and a bassist and changed their name to Irukandji, to reflect the harsher more aggressive nature of their music. Their style is heavily based on singable melodies, fast paced technical guitar solos and double-bass pedal drumming.
