The Black Crowes [ tickets ] look past a few cancellations to extend their current summer/fall tour into winter as the southern rockers continue their resurgence on the road.

The group canceled recent concerts in Las Vegas and Santa Cruz, CA, as well as tonight's planned gig in Mesa, AZ, "due to an unexpected illness within the band," according to The Black Crowes' website.

The band plans to reschedule the Las Vegas and Mesa dates, with tickets for the old date to be honored at the make-up show; the Santa Cruz date will not be rescheduled.

The Crowes are expected to continue their Western US swing tomorrow night (9/17) in Los Angeles, with additional West Coast dates to follow before the band mounts a long fall run of Eastern and Southern US shows, kicking off Oct. 5 in Alpharetta, GA. In December, the group returns to California for a five night run at The Fillmore in San Francisco. The complete schedule is included below.

The band is working the road behind its first studio album in seven years. "Warpaint," which surfaced earlier this year, debuted at No. 5 on The Billboard 200 chart, spawning three singles so far: "Goodbye Daughters of the Revolution," "Wounded Bird" and the recently sprung "Oh Josephine," which hit radio earlier this month.

The group--made up of brothers Chris Robinson (vocals) and Rich Robinson (guitars), along with Steve Gorman (drums), Sven Pipien (bass) and new members Adam MacDougall (keyboards) and Luther Dickinson (guitar)--took a four-year hiatus following its previous studio set, 2001's "Lions." The rockers returned to the live stage in 2005 with seven sold-out shows at New York City's Hammerstein Ballroom.

In July, the band filed a lawsuit against country singer Gretchen Wilson, claiming that she violated music copyright by copying the Crowes' 1990 hit single "Jealous Again" when she recorded her song "Work Hard, Play Harder."

"We find the musical verses of Wilson's song to be such an obvious example of copyright infringement that I expect all parties to reach a relatively quick resolution to avoid litigation," the band's manager, Pete Angelus, told Billboard at the time.
