A two-year hiatus sure hasn't damped fans' love for the Black Crowes.

Almost as soon as tickets went on sale for the "Lay Down With Number 13" 2013 world tour, most of the shows sold out prompting the band to add a second leg to the tour.

"We're thrilled and honored and look forward to sharing our music with everyone," frontman Chris Robinson said in a press statement about the tour, which included several two-night stands including in D.C., London, Chicago and New York.

The Southern rock band that built a huge fan base almost as soon as they launched 20 years ago, has a new line up this time out that includes: Robinson and his brother Rich Robinson (guitar, vocals), Steve Gorman (drums), Sven Pipien (bass), Adam MacDougall and new member Jackie Greene (guitar, vocals). But that doesn't mean the band won't give fans plenty of vintage Crowes as evidenced by last month's release of Wiser for the Time that contains 26 songs including some never-released-before versions.

"Some of the stuff on the album to the casual fan sounds a bit deeper into folk or bluegrass or country," said Gorman who has been with the Crowes -- except for a brief hiatus -- almost since the band's inception. "But our definition of rock and roll has always been blues plus country equals rock and roll. We have incorporated those sounds into [our music] for years."

The band is also touring behind Before the Frost, which was recorded in five days before a live audience that looked on as the band finalized and recorded.

"We had 200 people there with us," said Gorman of the recording sessions in February and March at Levon Helms Studio in Woodstock, N.Y. "We weren't putting on a show, we were letting people see how we record. My wife said later 'Watching those people's face as you guys worked was [interesting]. The way you guys never even say full words to each other but know exactly what you're saying to each other.' "

That almost telepathic communication is the result of Gorman and the brothers Robinson (Chris and Rich) melding with the other plays into a cohesive unit not unlike a close family.

Although the band members don't always agree on personal issues, they are very like-minded when it comes to music and the ever-advancing sound they want to present as the Black Crowes, he said.

"It's great when bands do one thing and really love it," said Gorman citing AC/DC as a group that presents one unique sound that can't be replicated by other bands. "The rule for us starting in 1987, the unwritten rules, was we just put down a new song, what's next? Let's keep moving. That is how we've always been."
