Laurie Anderson began a week of special performances with one very special concert indeed as she was joined by artist and activist Ai Weiwei, via Skype from his home in Beijing, for the premiere of the piece Greetings to the Motherland at Toronto's Luminato Festival last night. The free concert, which took place at David Pecaut Square and was webcast live, is now available in full below.

Anderson returns home to New York City to participate in two free events this Tuesday and Wednesday in Battery Park City's Rockefeller Park for the annual River to River Festival. She joins New York musicians, writers, and performers for two singular events exploring themes of transportation, politics, money, and love, featuring stories from United States Parts 1-4 with special guests Steve Buscemi and Young Jean Lee on Tuesday and a night of improvisation with longtime musical collaborators, including former Kronos Quartet cellist Jeffrey Zeigler, on Wednesday. In the case of rain, the events will be held at the Winter Garden of the World Financial Center. In addition to these concerts, Anderson has curated a number of events for the festival; for more information, visit rivertorivernyc.com

The New York Times' Allan Kozinn spoke with Laurie Anderson about all of these events and more for a feature article on her "Wall-to-Wall Summer" available at nytimes.com.
