This year’s Tribeca Film Festival (TFF) saw the rise of ticket prices to $12 from $18 and the premieres of chick flicks like “Lucky You” and blockbusters like “Spider-man 3.” For anyone who missed Spidey’s web-slinging adventures or just didn’t want to shell out so much money, the free short films festival Tropfest@Tribeca offers a night of music and cinema this Sunday, September 23 at the World Financial Center.

An import from Sydney, Australia, the annual short film festival debuted at last year’s Tribeca Film Festival with six new short films and another six from Australia’s festival. The great turnout prompted Tribeca Enterprises to make Tropfest a separate event.

Of the 16 films being screened this Sunday, New York-based filmmakers made 11. The festival also features films from Australia, England and Norway.

In the tradition of the Australian Tropfest, each short film incorporates the Tropfest Signature Item (TSI). This year the TSI is a “slice,” and filmmakers interpreted this theme both literally–four films feature pizzerias prominently–and figuratively (“slices of life”).

This year’s Tropfest also features live musical performances. Film screenings begin at 8 p.m., but DJ Shorty will be dropping some beats starting at 5 p.m. He will be joined by Haunt, an alt-country act, and Australian indie rockers Second Dan.
