意大利的DGM最初成立于1994年，最初是一种全功能的金属金属乐队，其特色是吉他手Diego Diego Reali，键盘手Maurizio Pariotti和鼓手Gianfranco Tassella。
1995年，前Raccomandata Ricevuta Ritorno的Luciano Regoli很快成为主唱。他们的第一个正式版本是1996年，即自制的迷你CD随机存取区。
1997年，乐队制作了他们的第一张全长专辑“ Change Direction”，该专辑在意大利，德国，芬兰和丹麦广受欢迎，这促使他们开始了意大利巡演，并因此受到欢迎。
随着新鼓手Fabio Costantino（前猛禽乐队）的出现，DGM进入了录音室，制作了第二张专辑：《时光之翼》（意大利杂志Metal Shock，Flash和Metal Hammer的顶级专辑）。在日本，CD的前10天售出了4,000册。Burrn也联系了乐队！进行独家采访，以扩大DGM在全球音乐界的声誉。
在发行第三张录音室专辑之前，Titta Tani加入了乐队，成为DGM的新歌手。Dreamland随后在2001年12月发行。2001年春季，Andrea Arcangeli（恐怖航空公司，Solisia，Concept，前变革河）在Dreamland促销活动的意大利日期之前成为了DGM的新低音播放器。
2002年，该乐队由意大利独立唱片公司Scarlet Records签约。Hidden Place于2003年5月发行，新的键盘演奏者Fabio Sanges（Abstracta）发出了新的渐进声音。第四张专辑收到了来自世界各地的许多杂志和网络杂志的好评。在发行之后，DGM在2003年的《金属之神》中演出。
2005年，Simone Mularoni取代了Diego Reali。Mularoni之前曾在Fear Studios担任音响工程师和制片人。加入他之后，DGM还与法比奥·桑格斯（Fabio Sanges）离开后与键盘演奏家Emanuele Casali合作。穆拉洛尼（Mularoni）和卡萨莉（Casali）为新歌赋予了新的录音过程，而西蒙妮（Simone）的经历的结果也包括在《异形》中，该专辑于2007年发行。
在现场直播中，DGM与Heaven＆Hell，Dream Theatre，Symphony X，Dark Tranquility等在Lagoa Burning Festival（2007），Prog-Power Europe（2007）中一起第二次在《神灵》中演出确认不同形状的高质量。
2007年2月，DGM宣布Mark Basile是该乐队的新歌手。蒂塔塔尼（Titta Tani）离开乐队后，他被选入意大利，欧洲和美国的几次试镜。
在2009年初，DGM与Mark Basile发行了他们的第一张专辑以及其职业生涯的第七张专辑：Frame。尽管获得好评，但一些评论将其标记为与Different Shapes相比略有退步。又过了四年，DGM发行了另一张录音室专辑，这是他们职业生涯中最长的差距。
2010年4月，DGM在罗马举行了一场演出，以庆祝该乐队成立15周年。该唱片与2碟CD / DVD Synthesis于同年9月录制并发行。DVD光盘包含完整的现场表演，包括后台访问和专辑“ Frame”的“制片”电影。CD是“最好的”唱片集，其中包含乐队整个职业生涯中的歌曲，并根据当前阵容重新录制和重新安排。CD还包含两首新歌“ Just like Before”和“ The Only One”。

DGM (“Diego, Gianfranco and Maurizio”, after the founding members) is an Italian progressive metal band. Over the course of the band’s history, they have had numerous line-up changes, with none of the founding members in the band’s current line up and eight previous members since 1994.
Early career (1994–2000)
Originally formed in 1994 as an all-instrumental, power metal outfit, Italy’s DGM featured guitarist Diego Reali, keyboardist Maurizio Pariotti and drummer Gianfranco Tassella.
In 1995 Luciano Regoli, formerly of Raccomandata Ricevuta Ritorno, soon joined as lead singer. Their first official release was in 1996, the self-produced mini CD Random Access Zone.
In 1997 the band produced their first full-length album ‘Change Direction’ the album was well received in Italy, Germany, Finland, and Denmark, which prompted them to start an Italian tour which resulted in a gain in popularity.
With the new drummer Fabio Costantino (ex-Carnal Raptor), DGM entered the studio for their second album: Wings of Time (top album on the Italian magazines Metal Shock, Flash and Metal Hammer). In Japan the CD sold over 4,000 copies in the first 10 days.The band was also contacted by Burrn! for an exclusive interview that enlarged DGM’s reputation in the worldwide musical scene.
Rise in Popularity (2000–2007)
Before their third studio album release, Titta Tani joined the band, becoming the new DGM singer. Dreamland was subsequently released in December 2001. In springtime 2001, Andrea Arcangeli (Airlines Of Terror, Solisia, Concept, ex-River of Change) became the new DGM bass player just before the Italian dates for Dreamland promotion.
In 2002, the band was signed by Italian independent label Scarlet Records. Hidden Place was released in May 2003 with a new progressive sound from the new keyboard player Fabio Sanges (Abstracta). The fourth album received excellent reviews on many magazines and web magazines from all over the world. Following the release DGM played at the Gods of Metal in 2003.
Misplaced was released in February 2004. The album was produced by Giuseppe Orlando’s Outer Sound studios. Like Hidden Place, Misplaced has been received well by both the magazines and the audience, and several live dates followed the release.
In 2005, Simone Mularoni replaced Diego Reali. Mularoni had previous experience as a sound engineer and producer at the Fear Studios. After his addition, DGM also teamed up with keyboard player Emanuele Casali after the departure of Fabio Sanges. Mularoni and Casali gave the new songs a renewed process of recording and the result of Simone’s experience is included in Different Shapes, which was released in 2007.
On the live front, DGM played for the second time at the Gods of Metal (2007) together with Heaven&Hell, Dream Theater, Symphony X, Dark Tranquility among others, Lagoa Burning Festival (2007), Prog-Power Europe (2007) as a confirmation of the high quality of Different Shapes.
Basile era (2007–present)
In February 2007, DGM announced that Mark Basile was the new singer of the band. He was chosen among several auditions throughout Italy, Europe and America after Titta Tani left the band.
In early 2009, DGM released their first album with Mark Basile and the seventh album of their career: Frame. Although well received, several reviews marked it as a slight step back compared to Different Shapes. It was another four years before DGM released another studio album, the longest gap in their career.
In April 2010, DGM performed a show in Rome to celebrate the band’s 15 year anniversary. This was recorded and released in September in the same year as the 2-disc CD/DVD, Synthesis. The DVD disc contained the complete live show including backstage access and a ‘Making of’ film of the album ‘Frame’. The CD is a ‘best of’ collection, containing songs from throughout the band’s career re-recorded and re-arranged with the current line-up. The CD also contained two new songs “Just like Before” and “The Only One”.
On 28 March 2013, DGM released their eighth album, Momentum. Their second with Basile and also the first album since 2004’s Misplaced to feature an unchanged line-up from their previous studio release. The album featured guest vocals on the track “Reason” from Russell Allen of Symphony X and guest guitars on the track “Chaos” from Jørn Viggo Lofstad of Pagan’s Mind.
On 26 August 2016, DGM released their ninth studio album, The Passage. Guitarist and producer Simone Mularoni said; “This album can easily be seen as our most ambitious work to date”. This album also featured special guest appearances, Evergrey singer Tom Englund on the track and single “Ghosts of Insanity” and another guest appearance from a member of Symphony X, this time from guitarist Michael Romeo on the track “Dogma”.
