A plethora of Chicagoland basement performances in high school was the spark to the Hush Sound’s fuse.

Seven years and three full-length albums later, the alternative-pop band will kick off its fall tour tomorrow in the group’s hometown of Chicago and then will point the tour bus west to the Hawkeye State.

The Hush Sound will perform 6:30 Saturday at the Blue Moose Tap House, 211 Iowa Ave. Tickets are $15.

The quartet is famous for its "baroque pop melodies" intertwined with "stunning female vocal interplay," and it has toured with a variety of musical superstars including Phantom Planet, OK Go, Rooney, OneRepublic, and the All-American Rejects.

The group has released three albums — So Sudden (2005), Like Vines (2006), and Goodbye Blues (2008) — and fans can look forward to new material dropping in 2013.
