[4] Peter Helmis, Joe Reinhart, and Colin Mahony met in Pennsbury High School and formed the precursor to Algernon Cadwallader, Halfway to Holland, with their friend TJ DeBlois (drummer of metalcore band A Life Once Lost.)

Reinhart and Mahony's collaboration with Like Lions was short lived due to musical differences, and subsequently reached out to Helmis and friend Nick Tazza (from Ape Up!)

"[6] Post-Breakup (2012–2022) In 2014, Reinhart, Helmis and Tazza, along with guitarist Nate Dionne of the band Snowing formed Dogs on Acid, who released one eponymous album in 2015.

[7][8] The re-issue contained what the band referred to as their "third LP", a compilation of their 2006 demo, the 2009 Fun EP and several b-sides and covers of instrumental Beatles and Beach Boys songs, "some of it we decided to record and put vocals on it.” Algernon Cadwallader has been herald for emo-revival in the mid 2000s and has consistently been praised for their math rock arrangements consisting of alternative tunings and off-time rhythm, earning spots on several "top lists" of emo bands.

The cover was in collaboration with Kinsella + Pulse, Theo Katsaounis and Bryce Pulaski with 100% of proceeds going to Palestinian Red Crescent Society.

[16] According to Ian Cohen of Pitchfork, the band "purposefully chose Midwestern emo over other forms of punk and hardcore, a choice that liberated from the professionalism, earnestness, and striving that defines indie rock.

[18] Joe Reinhart's guitar work in the band consisted of finger-tapping, arpeggios, harmonics, hammer-ons and pull-offs, odd time signatures, and capoed chord progressions.

The band's debut full-length album Some Kind of Cadwallader has been described as "technical", and has been noted to take stylistic cues from heavy metal in addition to math rock.
