Van Halen not only got back on the road in 2012, they also delivered a long-in-the-works and long-awaited new studio album. Released on February 7, A Different Kind of Truth was the band's first full-length effort featuring original frontman David Lee Roth since 1984's 1984 . Many of the songs on the collection harkened back to the sound of the group's heyday -- perhaps not surprising, since many of the tunes reportedly were based on recordings that dated back to the Van Halen's early days.
The tour, meanwhile, went smoothly -- at least at first. VH announced an initial North American leg that was scheduled from a February 18 show in Louisville, Kentucky, through a June 26 concert in New Orleans. Then, in April, the band revealed that the trek was to be extended until an August 12 gig in Cincinnati. However, in May, the added concerts were removed from the rockers' itinerary and the outing's end date reverted back to June 26.
Rumors began swirling that old animosities had reemerged between Roth and guitarist Eddie Van Halen , but the singer insisted that was not the case. In a video message to fans, Roth declared, "The band is getting along famously, [but] we bit off way more than we can chew when it came to scheduling."
Van Halen had intended to get back on the road in November with a tour of Japan, but Eddie suffered a serious health setback in August that delayed those plans. The guitar whiz underwent an operation for a severe bout of diverticulitis -- an inflammation of the colon. He's on the mend now, and the group is eyeing a return to touring in 2013.
Another major veteran rock act that unleashed its first new studio album in many a year was Aerosmith. Music from Another Dimension! , which was released November 6, is the band's first collection of all-new original songs since 2001's Just Push Play . The Boston bad boys kept plenty busy in the months leading up to the arrival of the album, which initially had been slated to hit stores in late August.
The Rock and Roll Hall of Famers kicked off their Global Warming World Tour with a North American leg that ran from a June 16 concert in Minneapolis through an August 8 show in Tacoma, Washington. About a month into the trek, singer Steven Tyler announced that he wouldn't be returning to his gig as a judge on American Idol , preferring instead to focus more on Aerosmith. As the release date Music from Another Dimension! approached, the band released several singles and promotional videos, as well as debuting a Web series about the making of the album.
To celebrate the release, the band members headed to their hometown of Boston, where they played a special free concert on November 5 outside of the old apartment building where they lived during the early days of the group. Aerosmith then launched a second Global Warming tour leg that ran from a November 8 show in Oklahoma City through a December 15 performance in Nashville.
Music from Another Dimension! was recorded with Aerosmith's old producer Jack Douglas at the helm. The record finds the band revisiting some of the different stylistic phases it's delved into over the years, from raw blues-rock numbers to catchy pop-rock tunes to soaring power ballads. Several guest stars make appearances on the album, including country superstar Carrie Underwood , John Lennon 's son Julian . and even Johnny Depp .
