Both of these shows appear to be going on sale this week! First of all, Ticketmaster.com has a listing for the April 21st Albuquerque, NM show where they post that presales begin Thu, March 6 at 10:00am and that general sales start Sat, March 8 at 10:00am.
arrowheadpond.com has a listing for Tori's April 19th concert in Anaheim, CA stating that general sales begin on Sun, March 9 at 10:00am. (They say Saturday, but I think they mean Sunday!) arrowheadpond.com does have a seating chart and ticket prices for Tori's show. The Anaheim, CA show will be at The Theatre at the Arrowhead Pond. This show has also been posted at Pollstar.com.
I have added all this to the Dent's Tour Schedule Page.
