The band featured TMV's bassist Juan Alderete de la Peña, Marcel Rodriguez-Lopez on drums and keyboards, and RHCP guitarist and Omar's frequent collaborator, John Frusciante. Their sole studio release, Sepulcros De Miel Maxi-EP ("Tombs of Honey" in English), initially came out on 30 May 2010 as a free download at Omar's official Bandcamp alongside Omar Rodriguez Lopez & John Frusciante duo collaboration with the option to donate any amount to "Keep Music In Schools" charity. (Subsequently, it became a regular digital album at a minimum price of $4.99.)
