Tim Archibald has been playing bass since he could crawl. As a rock bassist from Cleveland, Ohio, he moved to Boston in 1976 and attended Berklee for 4 years playing with Ralph Moore, Kevin Eubanks, Mike Stearn, Bruce Bartlett, Randy Roos in the local scene. Forming his own band Urge he played for 3 years with Fly By Night as a jazz migrant worker touring the south and east with Groove Holmes, Dobie Gray, Dizzy Gillespie and others. Played with John Butcher in 1984 on Capitol records, New Man, signed to Epic records in 1985 and quickly joined RTZ with the late, great Brad Delp, Brian Maes and David Stefanelli. Six more years with Peter Wolf from the J. Geils band Tim endorsing LaBella Strings, Harkte amps and Pedulla basses. Tim joined Ernie and the Automatics working for 6 years alongside the great Sibby Hashian on drums, touring with Deep Purple and teaching music to young students all over the place.

Around 1989, Delp was on hiatus from Boston and looking to get active in writing again. He contacted Goudreau about a possible collaboration and RTZ was formed. Goudreau and Delp brought in keyboardist Brian Maes who was part of the Orion the Hunter touring band, drummer Dave Stefanelli and bass player Tim Archibald. Maes and Stefanelli had previously worked with producer Nick Lowe in England and Archibald's band New Man had released an album on Epic.

Delp and Goudreau landed a deal with Giant Records and the first RTZ album, titled Return to Zero, was released in 1991. A video was produced for the first single "Face the Music". The band soon hit the road and Delp gave Boston his notice. After touring the US extensively, a video was prepared for the single "Until Your Love Comes Back Around" penned by keyboard player Brian Maes. The single was very successful and reached #1 in several markets, #26 in the U.S. Two other tracks, "There's Another Side" and "All You've Got" also got airplay, with the latter reaching #56.

RTZ felt that the band was not getting the attention it deserved by the label and asked to be released from their contract. As RTZ began to shop for a new label, Delp decided to leave the band and would eventually reunite with Boston for the Walk On tour. The other band members decided that it would be impossible to replace Delp and decided to end the band. The Return to Zero album went out of print until April 2013, although the band later released other material. There were still enough recordings left over from the original recording sessions to create another album. Barry searched for a new label and eventually found MTM Records. The recordings were released on September 28, 1998, and the album was titled Lost.

In 2004, Lost and Found was released. It features previously unreleased music from the band. In 2005, RTZ released two CDs simultaneously, Lost in America and Found in America under band member Brian Maes' Briola Records label. The album contains all the same material that was released on Lost, including the song "Dangerous", which was only available on the Japanese release of Lost. Found in America contains the same material that is on their 2004 release Lost and Found, but includes a bonus live version of the song "Return to Zero".

The Delp and Goudreau album was also released in 2004, and was included as a bonus CD in Lost and Found. It featured RTZ but was released under the name "Delp and Goudreau" and involves a different style of music from RTZ's albums.

In 2007, the band reunited (though with former Boston member Sib Hashian on drums) to release a single called "Rockin' Away". Written in 2006, it celebrated the 30 year anniversary of Boston, and is also an autobiography of Brad Delp's music career. Following Delp's suicide in 2007, the band reunited again to release the single "Set The Songbird Free" as a tribute to Delp, with Maes on vocals. They also performed at the Brad Delp "Come Together" tribute concert in 2008.

This entire line-up (with Hashian on drums, and without Delp) also makes up most of the members of the band Ernie and the Automatics which formed in 2006.
