DIO RULES, the ultimate tribute to Ronnie James Dio featuring Andrew Freeman on vocals, performed its inaugural shows this past Thursday and Friday in Annapolis, Maryland, and Lititz, Pennsylvania.

A two-minute promotional video from DIO RULES is also available.

The all-star band pays tribute to Dio by performing hits that cemented his legacy with Rainbow, Black Sabbath, and Dio.

Based in Las Vegas, Freeman is an American rock vocalist and guitarist who has played for several bands, most notably punk rock group THE OFFSPRING and hard rock guitarist George Lynch's LYNCH MOB.

Freeman joined THE OFFSPRING as a touring guitarist and backup vocalist on their 2008 tour for the album "Rise And Fall, Rage And Grace".

In 2010, Freeman joined HURRICANE as the lead vocalist, performing a few shows with the band before leaving in 2013.

In 2012, Freeman joined the original members of DIO as lead vocalist to form the band LAST IN LINE.

LAST IN LINE has released three albums so far: 2016's "Heavy Crown", 2019's "II" and 2023's "Jericho." Freeman has performed on several tours as the lead vocalist with George Lynch's LYNCH MOB, including a feature on "The Tonight Show With Jay Leno" and a headline show at the Musicians Institute in Hollywood, California.

In 2018, Freeman started performing as the vocalist for LIES, DECEIT & TREACHERY with Jimmy D'Anda, Mick Sweda, and Lonnie Vencent.

He also formed a band called DEVIL'S HAND with guitarist Mike Slamer.

In December of the same year, they released a self-titled album.

In 2021, Freeman filled in for FIREHOUSE lead singer C.J.

In May 2022, Freeman joined GREAT WHITE as the band's lead singer but lasted only five months before he was replaced by Brett Carlisle.

The tribute band is formed by guitarist Vivian Campbell, drummer Vinny Appice, and bassist Jimmy Bain — Ronnie James Dio's co-conspirators and co-writers on the "Holy Diver", "Last In Line" and "Sacred Heart" albums.

LAST IN LINE's initial intent was to celebrate Ronnie James Dio's early work by reuniting the members of the original DIO lineup.

When asked about the fan response to hearing him sing the DIO material live, Freeman stated in a 2019 interview with Metal Talk that it has been mostly positive, with no one approaching him directly expressing discontent.
