The news comes off the back of the annoucnement they were "thrilled" to sign a worldwide record deal with international label Silver Lining Music.
Diamond Head will be touring Europe for most of 2019 and are confirmed on the line-up of two very special UK shows with NWOBHM giants Saxon amid their busy schedule.
The new record, called The Coffin Train, will be released on May 24.
Frontman Brian Tatler said of the flurry of announcements: “We’re delighted to be bringing the Diamond Head lightning to our new family at Silver Lining Music and honoured to be standing alongside a stable of established international talent.
"This includes such legends as Saxon, Europe and Motörhead. This is the start of an exciting journey and we can’t wait to share it with you all.”
And speaking about their new signing, a spokesperson for Silver Lining Music said: “We are beyond psyched to announce that we have struck legendary heavy metal gold by signing Diamond Head to the Silver Lining Music roster.
"The blend of Brian Tatler’s legendary chops with the exciting new visions of Rasmus Bom Andersen are electric indeed, and we look forward to the world discovering that for themselves with Diamond Head’s forthcoming new album The Coffin Train, out on May 24.
"We are proud to offer you the chance to catch a ride on this train, so be sure to buy a ticket and get on-board fast!”
Formed in 1976 under the riff-rolling leadership of guitarist Tatler, Diamond Head would quickly establish themselves as a vanguard of the exploding NWOBHM scene.
