O-Town Reunites … Minus One Key Member

Just when you were thinking, “Hey, whatever happened to those guys from O-Town??” — TMZ has learned 4 out of 5 band members have reunited … and they’ve already begun to record new music!

Sources close to the band tell TMZ … Erik-Michael, Dan, Trevor and Jacob are back in the studio … sans one member who just didn’t feel like getting the band back together — Ashley Parker-Angel.

We’re told the guys — who were all plucked out of obscurity on the very first “Making the Band” in 2000 — have been kicking around the idea of a reunion for a while … and have spent almost a year trying to get Ashley on board.

But a few weeks ago — when it became clear Ashley wasn’t going to change his mind — the guys decided to officially move forward without him … and are now trying to work out some tour dates.

They want it all … or nothing at all.
