1990/01/28 Portland, OR Pine Street Theatre - While JAMC played this date, NIN probably didn't support, because of travel time involved. The first support date was probably Warfield in SFO.
<s>1990/03/27 Atlanta, GA - Were there 2 dates for The Roxy?</s> - yes, newspaper article confirms it
1990/04/03 Phantasy - Were there 2 dates for Cleveland?(probably not the 4th)
<s>1990/04/14 Washington, DC Lisner Auditorium - Did this one happen? The 9:30 Club headliner show the next night definitely did.</s> - Manifesto was opener. NIN did not open. [http://www2.gwu.edu/~alumni/yearbooks/CHERRY_TREE_1990_ST.pdf] 1990/04/17 Toronto - Concert Hall or RPM Club? Setlist.fm user says it was RPM club. alt.music.nin poster says first NIN gig in Toronto was RPM Club.
1990/07/12 Neptune, NJ, Green Parrot - This date originally solicited [https://happinessinheresy.com/nine-inch-nails-concert/philadelphia-july-12-1990/ 1.5 months] before as Chestnut Cabaret. Likely replaced by Drexel Univ. concert. Drexel and Chestnut Cabaret are located within 4 blocks of each other, so it's unlikely both happened. This guy's [http://musictravel.free.fr/concerts/concerts90.htm concert list] shows that he went to many early NIN shows around Philly and to many shows at the Chestnut Cabaret. If NIN had played Chestnut, he would have been there. Instead, he only went to Drexel. So I think that confirms that Chestnut was probably cancelled, maybe replaced by Drexel, and Green Parrot slotted into the original Chestnut date.
