As the number of members in a given band decreases, the worries of a “Ship of Theseus” transformation increase if band members join on or drop out. As such, Blink-182’s decision to slot in Alkaline Trio’s Matt Skiba in place of former vocalist and guitarist Tom DeLonge 14 years into their career must have elicited trepidation amongst many long-time fans. In “Bored To Death,” the first single off of Blink-182’s California, which is slated for a July 1 release, fans get a glimpse of Skiba’s contributions to the trio. The new collaborators have seemingly decided to pass on delving into radically new material in their first public debut, instead offering up a song that could easily slot into any of Blink-182’s most middle-of-the-road, polished releases (Enema of the State, Take Off Your Pants and Jacket). “Bored To Death,” however, evidences the darker, more mature tone that Blink-182 has started moving towards as its band members near their mid-40s.
