Very happy with my 'sea fantasy' reissue too. I thought there was some wierd noise reduction effecting the high end on the percussion after putting on the first track, but I think this is from the original recording as some form of filtering or phasing on the drums.
Phased drums seemed to be all the rage on the 70's library scene
