I had this DP Mk.IV vinyl album back in the day and even had it on cd back in the 1980s and contrary to some reviews saying it's more like 'Shallow Purple' I liked playing it LOUD!. The opening track Burn with Jon Lord on Hammond organ playing the main guitar riff over and over again filling in for guitarist Tommy Bolin's damaged hand sounds pretty good to me along with Tommy's guitar solo and the other tracks on side one are taken from the Come Taste The Band album like Love Child & Lady Luck along with Tommy's Wild Dogs all sound good to me on side one of the vinyl album. Side two has more established DP songs such as Smoke On The Water, Soldier Of Fortune & Highway Star but it is You Keep On Moving again from the Come Taste The Band album that is the 'killer track' on the album.
