The Deep Purple album Burn was released in 1974 and was the first album with lead singer David Coverdale and bassist/backing vocals Glenn Hughes. Coverdale's voice is very bluesy and Glen's Bass playing added some blues and funk into the mix. Blackmore pushed for a more blues type appeal for the MK3 lineup, however in this album it only dabbles in the blues with songs like Mistreated. At this point in time Deep Purple still kept that heavier more Classic Metal and Hard Rock appeal. Overall every song on the album is well done and provides incredible energy and creativity, except for maybe A200 as it give interlude vibes for a live show, but when in the right mood can be enjoyable. The album is overall still quite heavy before much of the funk took over and is great for fans of early metal and hard rock. Burn as a title track has one of the best riffs Blackmore has ever done and it is one of the pinnacles of Deep Purple.
