Just a couple days after Eric Avery backed out of Nine Inch Nails, the industrial rockers have recruited former member Robin Finck to rejoin the group. NIN mastermind Trent Reznor revealed the news in a tweet to his fans.

Eric Avery, best known as the founding bassist of Jane's Addiction, decided to exit Nine Inch Nails after being announced as a new member of the revived group earlier this year. Avery stated he was overwhelmed by the band's touring commitments.

The initial list of bands playing Chicago's 2013 Riot Fest has been unveiled and it features a number of prominent punk, rock, alternative and metal acts. Fall Out Boy and Blink-182 are two of the three headliners, with the third act a mystery as of now.

The three-day event, taking place Sept. 13-15 in Chicago's Humboldt Park, will also feature such bands as Violent Femmes, Motorhead, Rancid, AFI, Sublime With Rome, Pierce the Veil and the Devil Wears Prada, among dozens of other acts.

As I Lay Dying have officially dropped off their upcoming North American tour with Killswitch Engage, and the news comes as no surprise as AILD frontman Tim Lambesis remains incarcerated on alleged murder-for-hire charges.

The band made the announcement on their Facebook page, stating: "In light of recent events, As I Lay Dying will unfortunately not be taking part in the upcoming tour with Killswitch Engage. Given the circumstances, we feel that it is best for the band to be off the road while the current situation gets sorted. We'd like to thank all of our fans for their ongoing support at this difficult time."

Today (May 16) marks the third anniversary of Ronnie James Dio's death. The iconic Black Sabbath / Rainbow / Dio / Heaven & Hell vocalist gave his all to music for over 50 years before succumbing to stomach cancer in 2010. To celebrate the live of Ronnie and to mourn his passing, the singer's widow, Wendy Dio, released a tribute to her late husband.

No vocalist in rock and metal history can claim a career quite like Ronnie James Dio's. After playing in various projects including Elf, former Deep Purple guitarist Ritchie Blackmore recruited Dio to front Rainbow in 1975. The singer's booming voice put himself in the periphery of Black Sabbath, who invited Dio to take the place of Ozzy Osbourne after the 'Prince of Darkness' was fired by Tony Iommi in 1979.

Two weeks after the tragic passing of legendary Slayer guitarist Jeff Hanneman, the band has announced a memorial celebration to honor his legacy. The event will take place at the Hollywood Palladium in Los Angeles on May 23.

Hanneman died on May 2 at the age of 49. Despite a battle with necrotizing fasciitis that was apparently contracted from spider bite, the actual cause of death was revealed to be alcohol-related cirrhosis of the liver.

Nine Inch Nails have just lost their new bassist. Eric Avery, who formerly played the four-string for Jane's Addiction, has left Nine Inch Nails after feeling "overwhelmed" by the band's upcoming tour schedule.

Nine Inch Nails frontman Trent Reznor made the announcement of Avery's involvement with the band in February of this year, but just as quickly as Avery joined Nine Inch Nails, he's pulled out of NIN's touring plans, leaving a vacancy in the group's lineup. Avery broke the news publicly via his personal Facebook account, making it clear that his decision is a bittersweet one.

The past year of Randy Blythe's life has been a roller-coaster ride of emotion. After being jailed in the Czech Republic on accusations of manslaughter stemming from a 2010 concert incident, the Lamb of God singer was found not guilty on all charges in March of this year.

Now, as Lamb of God are set to kick off a North American tour tomorrow (May 15), Blythe reflects on the events of the past year and remembers the 19-year-old fan who died from a fall at that 2010 concert. He also asks fans to be cautious when they attend metal shows. Below is a portion of Blythe's essay, with a link to the entire piece below:
