Pittsburgh has lost one of its best and most-traveled hard rock/metal bands.

Carousel, which released the excellent second album "2113" last September on the prestigious NYC label Tee Pee Records (Sleep, Witch, Graveyard) and toured internationally, announced Monday that it is disbanding.

Frontman Dave Wheeler posted on Facebook, "Hello fans and friends... It's difficult to make this post but the time has come for carousel to call it quits. It's been a hell of a ride but frequent lineup changes and other unfortunate events have necessitated this decision. Thanks to anyone who supported us over the years. We're still humbled by the fact that anyone gave a crap about us or our music and we're truly grateful to our label Tee Pee Records for taking a chance on us. Jim and Dave will carry on with their other band Outsideinside. We leave you with a clip of Jeweler's Daughter live in Bilbao, Spain from our last tour. Again, thank you from the bottom of our hearts. It's been a dream come true."

Carousel, which formed in 2012 with members from 70,000 BC, Magic Wolf, The Karl Hendricks Trio and Mary Celeste, was divided between Pittsburgh and Philadelphia when it replaced departing guitarist Chris Tritschler with the Philly-based Matt Goldsborough from '70s metal pioneers Pentagram. Also, soon after the album was released last year, Carousel abruptly parted ways with enthusiastic drummer/founding member Jake Leger.

As noted, Wheeler and bassist Jim Wilson will continue in Outsideinside. Wheeler and Goldsborough could not be reached for further comment early Tuesday.

Dave Wheeler tells us when Goldsborough left the band after the last tour, "It was just getting harder to keep a lineup together. We ended up getting fill-ins on drums and guitar for our last tour but that's not sustainable... Also, one of those guys was from Boston and one was from New York. We thought about getting a band together made of just Pittsburgh heads but the thought of teaching another lineup these songs was really unappealing. I guess we could have taken a break and seen if we wanted to continue later but I thought it would be best to make a clean break. That way we can all move ahead with other things."
