✔️1990/04/17 Toronto - Concert Hall or RPM Club? Setlist.fm user says it was RPM club. [https://groups.google.com/d/msg/alt.music.nin/dH6Dscu98wc/52RxD_tASqgJ alt.music.nin poster] says first NIN gig in Toronto was RPM Club. UPDATE: Solicitations were for RPM: https://happinessinheresy.com/nine-inch-nails-concert/toronto-april-17-1990/
1990✔️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. UPDATE: Green Parrot was a MBM headlining date: https://www.echoingthesound.org/community/threads/5398-Happiness-in-Heresy?p=492002#post492002
1990✔️1990/07/25 St. Louis, MO 1227 - unlikely they played the same venue within a month of each other. The 6/21 date is confirmed with newspaper solicits, and this one has none. Only possibility is if the 6/21 date got postponed for some reason (first night of the tour) and made up on 7/25? NIN Historian listed 7/25 without any corroboration, so maybe he knew the concert took place, but not the date, and slotted it in somewhere it might fit, but he didn't know it was at the beginning of the tour? UPDATE: There is zero for "1227 nine inch nails" on newspapers.com in July 1990, and tons in June 1990, so I think this date is just flat out wrong. UPDATE 2: This was a MBM headling date: https://www.newspapers.com/clip/49206028/st-louis-post-dispatch/
✔️1991/01/22 Washington, DC 9:30 Club (1 AM show) - <s>What was the proof for 2 shows on the same night? I forget.</s> 9 PM and 11 PM shows: https://happinessinheresy.com/wp-content/uploads/2019/08/026-AUE-1991-01-28-001-SINGLE-1.jpg
