Styper have been together for at least 10 years now. Putting out albums. Playing shows.
In 2003 they were back together and touring. They released a 'best of..'
In 2004 they released a live album from 2003 they recorded.
IN 2005 they did their first studio album since the breakup, Reborn.
In 2006 they released extended versions.
In 2007 they released a Greatest Hits Live in Puerto Rico, and also their original demo's when the band was called Roxx Regime.
In 2009 their next studio album Murder By Pride.
In 2011 they released The Covering, a cover album of their influences and favorites. Bands like Judas Priest, Iron Maiden, etc..
In 2013 they released Second Coming, a re-recording/reworking of a selection of songs from their original time together from Yellow and Black Attack up til Against The Law.
In 2013 i believe they are also scheduled for a new studio album.
They have been touring this whole time, even outside the US. The bass player quit for a while, during all this. He was replaced by a guy who was in a band called Seriah, back in the day. But now the original bassist is back.
Also, many of these guys have been in other bands. Michael Sweet, the singer, did a number of solo albums, and sang for... i think it was Boston for a bit. Touring.
Robert Sweet did a solo album called Love Trash, as well as a hired studio drummer for a number of other albums. He was shortly in bands like King James, Blissed and others.
Oz Fox, guitarist, was in Sin Dizzy and joined Bloodgood for a while.
Tim Gaines, bassist, was also in Sin Dizzy and King James.
So yeah, these guys haven't really stopped, whether it's been Styper, or some other band.
