The former American Idol runner-up returned with "Underground" as another preview of his forthcoming album which is due out next month, reported Ace Showbiz.
"Underground" is a slow-tempo piano-driven ballad and Lambert, 33, sings about getting lost without his significant other.
Produced by hitmakers Max Martin and Shellback, "The Original High" is led by single "Ghost Town" and is scheduled to hit stores on June 16 via Warner Bros Records.
The piano-driven ballad is the second song to have surfaced from the full-length album.
