Marasigan formed the indie rock band Sandwich in 1998, which provided a grittier, more experimental sound compared to Eraserheads.

Marasigan recently formed the supergroup Party Pace in 2022, drawing influences from surf rock, dream pop, and post-rock.

[4] He invited Zabala and fellow freshman Marcus Adoro for a jam session at Alberto's rehearsal studio in Cubao, but nothing materialized.

They performed covers of British new wave acts such as The Primitives, The Bolshoi, Gene Loves Jezebel, The Soup Dragons, and The Housemartins.

[4] Dela Peña eventually left Sunday School to pursue jazz, leading Marasigan to bring in Zabala and Adoro.

Marasigan and Buendia combined Sunday School and Curfew into a new band, which they named Eraserheads after the David Lynch film.

In 2002, vocalist-guitarist Ely Buendia left the Eraserheads, and Kris Dancel from the all-female band Fatal Posporos was recruited to fill the vacancy.

On August 30, 2008, at the Fort Bonifacio Open Grounds in Taguig, Marasigan joined Buendia, Adoro, and Zabala for The Eraserheads reunion concert.

Pedicab's first album Tugish Takish (the name coming from onomatopoeia of the sounds made by banging on drums) under Vicor music was released later that year.

Tugish Takish has spawned hits such as "Dito Tayo Sa Dilim", "Dizzy Boy", "Konti Na Lang" and "A Stormy Night".

In 2008, Marasigan launched his new album with Sandwich, after that, he also launched a one-shot band called "Project 1" with Clem Castro (former Orange and Lemons, now The Camerawalls) on guitars, Francis Reyes (The Dawn) also on guitars, Carlos Calderon (Chicosci) on bass, Jazz Nicolas (Itchyworms) on drums and Uela Basco (Chilitees), Katwo Librando (Narda/Duster) and Marasigan himself on vocals.

Squid 9 is a hip-hop influenced band that started out as a studio act and is formed from members of the Eraserheads, Monsterbot and Sun Valley Crew among others.

Squid9 Live is composed of Marasigan on samplers, drum machine and Chaos Pad), Vin Dancel (Twisted Halo and Peryodiko) and Kathy Meneses (Daydreamcycle) on vocals, Buddy Zabala (The Eraserheads, The Dawn, Twisted Halo & Cambio) on bass, keyboards and samplers and Rann Golamco (Drip, Porta, and formerly of Mojofly) on guitars.

He is also part of Sun Valley Crew, a hip-hop/rap group with members Ryan Armamento and RJ Seneres on vocals, Uela Basco also on vocals, Mong Alcaraz on guitars, Dan Gil on Rhodes keyboards, Dex Aguila on Drums, Raimund Marasigan on samplers and Ryan Ventura on bass.

He is often dubbed as "The Philippines' busiest musician", with multiple but different, simultaneous bands, in addition to collaborations with various artists such as Francis Magalona, The Pin-Up Girls, Rivermaya, Keltscross, Sugarfree, Itchyworms, Chicosci, Freestyle, Wolfmann, The Dawn, Chillitees, and others.

Marasigan is the bassist and percussionist of the new band called Gaijin, fronted by Jesse Grinter (guitars and vocals) and Shinji Tanaka (drums).

Marasigan also launched Assembly Generals in 2015, which is dubbed as "Raw Electric Filipino Hiphop", with members Paolo Toledo, Mon Punzalan, and Deng Garcia.
