There are multiple artists with the name Bad Habit. 1) Bad Habit is a Swedish hard rock band founded in 1986. 2) Like many great punk records, this one’s almost over before it starts. While this isn’t quite great, it does cover all the hardcore bases: fast, loud, aggressive. The four song demo clocks in at just 5:39, but it lets up very little over that time. Bad Habit draws a lot from Minor Threat with just a slightly looser approach a la early Black Flag.
