I recently noticed the collection Original Album Classics featuring five repackaged Isley Brothers albums (Brothers Isley (1969), Get Into Something (1970), Giving It Back (1971), Brother Brother Brother (1972) and 3+3 (1973)). I believe the cd's featured in this collection are the same as the ones that were issued in 1997. I'm wondering if these discs have been remastered?

I was considering buying this set when it was released last year,but I ended up buying all of their CDs individually instead,which really are remastered (except for 'Go For Your Guns',their only 70s album that hasn't been remastered yet).
