Video footage of guitarist/vocalist Michael Sweet of Christian hard rockers STRYPER performing an acoustic version of the song "Passion" on October 2 in Cranston, Rhode Island can be seen below.STRYPER recently spent time in the studio recording 17 songs for a new album that will be released in 2012. Michael Sweet previously said, "We're tracking 17 songs 14 old classics, three brand new songs ['Bleeding From Inside Out', 'Blackened' and 'How To Live']. We're doing the record in phases, a little at a time. It won't be mastered until January, which means it won't be available until sometime after that. We're funding this ourselves, so it's a tedious, time-consuming task that we have to do in phases due to extensive touring and other things going on between now and the end of the year." STRYPER's covers album, "The Covering", sold around 4,600 copies in the United States in its first week of release to debut at position No. 175 on The Billboard 200 chart. The band's previous CD, 2009's "Murder By Pride", opened with 5,900 units to land at No. 73. Produced by frontman Michael Sweet, "The Covering" is unlike any previous STRYPER recording in that it's a collection of cover songs from bands that inspired them and helped to shape their sound and musical identity, including hits from JUDAS PRIEST, IRON MAIDEN, LED ZEPPELIN, KANSAS and many others. "The Covering" will also include "God", a new original recording from STRYPER.
