After the great "On The Seventh Day God Created... Master", Master returned in 1993 with a new effort entiled "Collection of Souls", basically a bit more Thrash Metal in style. It is hard to find a band that started as a Death/Thrash one in a period of Thrash Metal and becomes Thrash in a period of Death Metal! Well, Master did it with this album. The tracks here, even if less Death Metal as on "On the Seventh Day God Created... Master", are really enjoyable. The first thing you will notice is the production: a bit more clear and Thrashier. The guitars are not so tuned down anymore and the vocals are less growling. The opener "Constant Reminders" is still in old school style Death/Thrash; a song that could easily have fitted well in Master's previous works with the fast bass drum and up tempo. Most songs that follow are Thrashier and even have a bit of punkier approach, going straigh ahead. A cool different song is the nice Thin Lizzy cover of "Jailbreak", Master goes Hardrock. The super-fast "Silver Spoon" is once more a good piece of brutal Death/Thrash and a perfect track to end this album. "Collection of Souls" is an effort that is surely more Thrash Metal than Death Metal but with lots of enjoyable moments.
