Hanson hit a bunch of major milestones last year: It marked its 25th anniversary as a band, as well as the 20th anniversary of its eternal hit "MMMBop," and it became the first (and, so far, only) artist ever to perform two Tiny Desk concerts in one day.

Now that it's officially in its second quarter-century — and, one hopes, long past having to remind people that it's been a terrific and criminally underrated band since the beginning — Hanson is attempting to one-up itself with the Nov. 9 release of a double-album called String Theory. The concept: Isaac, Taylor and Zac Hanson revisit their catalog, and perform new and/or previously unreleased songs, while backed by a symphony orchestra. (The pieces are arranged by Oscar winner and composer David Campbell, a.k.a. Beck's dad.)

The band will tour North America this fall — accompanied by an assortment of local orchestras, including the National Symphony Orchestra — but in the meantime, you can watch Hanson perform the simultaneously hooky and haunting "Siren Call" on this page.
