Sunday CALENDAR SECTION only of the Los Angeles Times, June 18, 1989

* Early American "Grunge Rock" band 
* Al's Bar performance notice - "Bleach"
* Curt Cobain - Chad Channing - Krist Novoselic

Often revered as the undisputed "bible" of Hollywood, the Sunday Calendar section occupied a rare space in journalism where a single publication could simultaneously dictate global entertainment trends and govern the inner workings of show business. Today, physical copies are an absolute rarity, largely because they were printed on standard, ephemeral newsprint designed to be devoured and promptly discarded at the end of the week.
Page 79 has a some continued music performance notices at less known area music venues with one night featuring: "Claw Hammer, Nirvana, Stone by Stone with Chris D." Though very small and discrete, this was the very first performance by NIRVANA at the capital of the entertainment industry. Very historic in the new alternative rock genre of the late 1980's & 1990's. (see images)
I suspect this to be an extremely rare item because their was really no reason to save it at the time.
Complete Calendar section only with all 96 pages, tabloid size, great condition.

Background: This tiny advertisement captures a pivotal, lightning-in-a-bottle moment when the tectonic plates of alternative rock were just beginning to shift. Occurring a mere nine days after the release of their debut album Bleach, Nirvana's June 1989 performances at Rhino Records and Al's Bar marked their official introduction to the influential Los Angeles music scene and served as a gritty blueprint for the impending grunge revolution. At this exact flashpoint in time, the band was a volatile, four-piece unit—featuring short-lived second guitarist Jason Everman and drummer Chad Channing—playing to sparse, unsuspecting crowds of underground punks just two years before Nevermind would completely demolish the mainstream hair-metal paradigm. For music historians and collectors, this specific newspaper section is a definitive "Holy Grail" artifact; it provides tangible, real-time print evidence of a legendary band at its most raw and unmanufactured, completely unaware they were on the precipice of altering rock history forever.
