Fido is the name of multiple musical acts, but one well-documented use of the name refers to a Canadian post-hardcore band from Winnipeg, Manitoba, active in the mid-2000s. That Fido combined elements of post-hardcore, punk and emo, featuring energetic, guitar-driven arrangements, emotive vocals and a focus on melodic hooks alongside aggressive dynamics. The group's work reflected the DIY ethos common to the independent rock scene of the era, with concise songs structured around driving rhythms and layered guitar textures. Their period of activity and releases are associated with the mid-to-late 2000s regional alternative scene in Canada.
