Sarah McLachlan at Lilith Fair in 1998 at Canterbury Park

Ticket sales for the return of Lilith Fair have been so slow that events have been cancelled in Phoenix and Nashville. The Twin Cities show is merely downsizing, moving from outdoors at Canterbury Park Festival Field to indoors at Target Center on July 18.

Tickets sold for Canterbury -- both reserved and general admission-- will be honored at Target Center.

This is the first time that founder Sarah McLachlan has taken Lilith, which presents female singers and musicians, on tour since 1999.

The Minneapolis event will feature Kelly Clarkson, Heart, Mary J. Blige, Metric, LaRoux and, of course, McLachlan.

The lineup varies from city to city. Among the other performers this year are Sheryl Crow, Erykah Badu, Colbie Caillat, Emmylou Harris, Corinne Bailey Rae, Jill Scott, Rihanna, Court Yard Hounds, Loretta Lynn, Cat Power, Miranda Lambert, Sugarland, the Bangles, Selena Gomez and Carly Simon.
