Mother lode is a principal vein or zone of veins of gold or silver ore. The term is also used metaphorically to refer to the origin of something valuable or in great abundance.
Mother Lode is the fourth studio album (fifth release overall) by singer/songwriter duo Loggins and Messina, released in late 1974. It was their final album with their original backing band, because multireedist and violinist Al Garth would soon leave the band, but multireedist Jon Clarke, bassist Larry Sims and drummer Merel Bregante remained, and saxophonist Don Roberts made his debut on this record. Future Toto keyboardist David Paich plays keyboards on this album while percussionist Milt Holland is augmented by Victor Feldman and the album was recorded on location at Jim Messina's California ranch. The Jim Messina composition "Keep Me in Mind" was sung by bassist Sims, whom Messina praised for having a phenomenal voice in a 2009 interview with Loggins for KCTS-TV.
