U.D.O. — the German metal band fronted by former ACCEPT singer Udo Dirkschneider — has commenced work on the follow-up to 2015's "Decadent" album for a tentative late 2017 release. In a new video message, Udo offered an update on the new disc writing sessions, saying: "We are working already, yeah, you can say, nearly one week on the new album, and what can I say? I mean, it will be — you can believe me — a really, really good album coming up [with] a lot of good songs. And watch out." Finnish guitarist Kasperi Heikkinen recently left U.D.O. for personal reasons. Udo spent the last year touring under the DIRKSCHNEIDER banner, performing classic ACCEPT songs for the last time. "Decadent" was released in Europe in January 2015 via AFM. The disc was recorded in Udo's current home, Spanish island Ibiza, and also at Redhead Audio Productions in Wilhelmshaven. The current U.D.O. lineup includes Udo's 23-year-old son Sven Dirkschneider, who joined the group as the replacement for drummer Francesco Jovino. DIRKSCHNEIDER released a live album called "Live - Back To The Roots" in October via AFM Records. The effort, which was recorded on April 2, 2016 at Kaminwerk in Memmingen, Germany, was made available as two-CD digipak and gatefold three-vinyl in four different colors (black, gold, silver and clear).
