Here are a few of mine. Not necessarily old school or metal.
Abnormal Thought Pattern - Altered States of Consciousness (Instrumental prog metal from Zero Hour Tipton brothers)
Al Di Meola - Elysium (Al Di is rocking again!)
Beardfish - +4626-COMFORTZONE (Prog Rock)
Benjamin Clementine - At Least For Now (Singer Songwriter)
Echolyn - I Heard You Listening (Prog Rock, wonderful album )
Kamelot - Haven
Mother’s Finest - Goody 2 Shoes & the Filthy Beasts (New hard rock album from the true old school)
Native Construct - Quiet World (Prog rock/metal from new band. Damn good)
Pantomimed - Searching For Eternity (Bulgarian prog metal 3th album)
Pat Travers - Retro Rocket ( Like Al Di, Pat is hard rocking again!)
Sammy Hagar & The Circle - At Your Service (Van Halen/Monstrose/Hagar songs live done well)
Steven Wilson - Hand, Cannot, Erase (Prog rock pure genius)
Symphony X - Underworld (If you have not heard of Symphony X crawl back under the rock you came from)
