Hardcore metal bands Widow Sunday and In the Kingdom of Nightmares will perform at R Space at R Space at Lincoln Street Center Saturday, July 17 from 6 to 10 p.m. on the lower level of 24 Lincoln St.

Opening will be the Midcoast’s Trediah and Salvo. The dance/concert is chem-free and for all ages; those younger than 14 must be accompanied by a guardian. Admission will be $6 at the door.

Intense, powerful, angry and brilliant, Widow Sunday has taken the metal genre to the next level of devastation with its latest offering, “In These Rusted Veins.” Combining the best elements of hardcore, industrial and metal, Widow Sunday delivers a pure dose of aggressive perfection that will stand up to its peers in the heavy music genre. Hailing from central Massachusetts, the quartet already is making a name for itself in the Northeastern metal scene. The self-described “dance metal” powerhouse has performed countless regional concerts in addition to receiving worldwide radio airtime.

In the short time In The Kingdom of Nightmares has been together, it quickly has begun to make a name for itself within the New England music scene with a relentless live show, sing-along breakdowns and a fast, stompy infusion of metal and hardcore. ITKON consists of TJ Washburn on vocals; Miles McIntire on guitar and vocals; Gary Porter on drums; Chris Manos on guitar and vocals; and Asa Hemenway on bass and vocals.

Salvo is from Southwest Harbor and in the spring of 2008 released its first full- length effort, “The Descent,” recorded with the infamous Swamp Donkey, engineer and producer of many of New England’s premier metal acts. In 2009, they began working on a second full-length album with a brand new lineup.

Trediah formed in late June, early July of 2009 from the ashes of longtime deceased nu-metal band Childhood Nightmare and more recently disbanded psychedelic folk metal band A.V.o.D. This powerful lineup developed a true stoner groove metal sound, coupled with the drive and determination to fulfill their desires to compose and perform heavy and rock hard.  Trediah is Travis “Herb” Carter on guitar and vocals; Roger “deadengone” Turner on guitar; Jeremiah “J” Aldrich on drums; and Fred “332” Wigglesworth on bass and vocals.

Coming up at R Space is Maine’s premier indie band Lost on Liftoff Saturday, Aug. 14; and Boston ska band The Have Nots Saturday, Aug. 21.
