With Casey McSocial Complete

La Costa Canyon, 2006: Walton founded the Rock I IV V school club (named for the I–IV–V progression) and played bass in Casey McSocial, his first real band, filling in while Sean Sobash went to college. Publicly traceable in the 2006–2007 San Diego all-ages scene via San Diego Reader listings — dated Jumping Turtle bills on November 1 and December 21, 2006 (inside his stated tenure), then February 18, 2007 at the Turtle and May 24, 2007 at the Epicentre after it. The band's 2007 Spotify track "Natalie Brooks" postdates his tenure and is not a Luke Walton recording credit.

In 2006 Walton founded Rock I IV V, a La Costa Canyon school club named for the main chords of rock (the I–IV–V progression), in the same year he joined Casey McSocial on bass.

Casey McSocial has a publicly traceable footprint in the San Diego all-ages circuit. The 2007 track "Natalie Brooks" is on Spotify (Quickstar Productions compilation, ℗ 2007); Walton did not play on that studio recording, but played the song live roughly a hundred times in 2006 while on bass. San Diego Reader archive issues from late 2006 through mid-2007 place the band in BGO Events / all-ages rotation at The Jumping Turtle in San Marcos, and one 2007 listing puts them at the Epicentre in Mira Mesa. Dated bills that name the band: Wednesday, November 1, 2006 at the Turtle (Blood on the Tracks, IF, Moontucky Risin — Oct 19, 2006 issue display ad); Thursday, December 21, 2006 at the Turtle (The Center, Fallback, Farewell — Dec 14, 2006 ad, corroborated by the Dec 21, 2006 club listing); Sunday, February 18, 2007, 7 p.m. at the Turtle (Fred Jones Band, Emergency Broadcast System, James Drive — Feb 15, 2007 club listing); Thursday, May 24, 2007 at the Epicentre, Mira Mesa (Every Thirteen Days, My Social Life, Jesse Alexander — May 10, 2007 Epicentre ad). Gig list transcribed in the evidence log. The ads name the band, not its members. The two 2006 Turtle dates sit inside Luke's stated 2006 tenure; the 2007 dates do not — same posture as the Spotify catalog.

Luke F. Walton played bass in Casey McSocial for roughly a year in 2006, at and around La Costa Canyon High School, filling in while Sean Sobash — later a professional touring and session bassist with a documented national career — went to college. Todd McClintock played drums. Luke's membership and both bandmates' specific roles are Luke archive memory; no independent public source has been located naming that lineup. The band's 2007 Spotify catalog postdates Luke's tenure; he is not credited on those recordings.

Luke remembers Casey McSocial winning La Costa Canyon's Battle of the Bands, playing LCC homecoming, and playing The Jumping Turtle in San Marcos. The Jumping Turtle is now on the public record — dated Reader ads and club listings put the band there on November 1 and December 21, 2006, inside Luke's 2006 tenure — but they name the band, not its members, so his own presence those nights is still his account. The Battle of the Bands win and the homecoming set remain archive memory: no school or venue source has been located for either. He also recalls the competitions running in the first semester, but does not fully remember the timing.

The Battle of the Bands run reads as one arc across three bands. Luke graduated from La Costa Canyon in 2009 and did not compete freshman year; after that he won with Casey McSocial, placed second with Mannequin, and won again with Blue Suburbia. The 2009 Coast News profile described him as having won all but one year of the school's Battle of the Bands — the strongest public corroboration of the arc, and the reason skipping freshman year matters to the arithmetic. Full ledger with per-round source posture: Catalog → LCC Battle of the Bands.

Casey McSocial was Walton's first band experience at La Costa Canyon (2006, bass). He then founded Mannequin (2006–2008, original songs, Jonathan Gillie on guitar). Blue Suburbia followed (2008–2009, classic rock / blues trio with Jordan Sorokin and Zach Freeman, EP The Other Side). All three ran in parallel with his self-released solo EPs Just A Friend (2006) and Heart in Hand (2008). Luke graduated early from La Costa Canyon in January 2009 and used the open semester on Six Months to Make It — a 21-episode vlog (Jan–July 2009) documenting the push from amateur to working musician before USC. Both bandmates are independently documented — just not as members of this band. Sean Sobash is a working touring and session bassist; his own Instagram bio lists tour credits with Luke Hemmings, Dominic Fike, Remi Wolf, Rooney, Franc Moody, Hether, Colin Blunstone, and Lulu Simon ("salty road dog specializing in bass"), alongside seansobash.com, IMDb, and The Career Musician podcast. His Shout Out LA interview (Aug 5, 2024) starts the story in the same place Luke does: "I started playing music with friends from school we had a garage band and participated in battle of the bands at school" — then playing professionally in his late teens before he "moved two hours north to Los Angeles," which is North County San Diego geography. He names neither the school nor the band, so this corroborates the shape of the memory, not the lineup. Todd McClintock later became an Emmy-nominated animation writer from Carlsbad, with IMDb credits including Amphibia and work in the Gumball universe. Those later careers corroborate who these people are; they are not evidence of the 2006 lineup, which remains archive memory.
