When we first were told about Party Poison, we couldn’t really believe that in 2015 there was a boy band in existence in Baltimore (well . . . Hagerstown), nor could we understand why they seem to play at the Ottobar and other area clubs so often. Then we saw them, and we totally got it. Discovered in obscurity at some local battle of the bands and championed by the Otto staff, these five gents all have an outsized love for the genre that sometimes outpaces their vocal or choreography skills, but they are unironically excited to perform and have genuine charm—which goes a long way to making their performances a face-splitting, head-shaking good time.
