Bandcamp A three piece from Boone, North Carolina, seven songs, thirty five minutes. The band describe Castle as Mean Green at full strength and promise towering riffs, crushing grooves and stories pulled from real life and tall tales. The riffs are there. What interests me is where they let the record move and where they refuse to.
The plateau
Put the seven tracks in order and measure how far each one travels between its quietest passage and its loudest. “Castle” opens at twelve and a half decibels. Then four tracks in a row sit between four and three tenths and six and one tenth: “Sludge Puppy”, “Employee Of The Month”, “Wild Bill”, “Slack Jaw”. One and eight tenths of a decibel separates the widest of those four from the narrowest. Then “Cyclone” goes to eight and three tenths and “Wastland” closes at ten and six tenths.
So the album is a wide opener, a long flat middle and two tracks of letting go at the end. The flat middle is four of the seven songs and twenty one of the thirty five minutes, which is sixty percent of the record spent at one level of push.
On a sludge record that is where a band is supposed to plant its feet rather than a sign that nothing is happening. It is also a lot of planting.
”Employee Of The Month”
Track three is six minutes twenty three, the longest piece on the album, and it sits at the edge on three axes at once.
It has the lowest spectral centre at 2479 Hz, against a top of 2999 on “Sludge Puppy”. It carries the most energy below 250 Hz, twenty nine percent, where nothing else gets past twenty seven. And it is the tightest thing on the record at four and three tenths decibels of range.
So the longest track is also the darkest by spectral centre and the most bottom heavy, and it is the tightest of the seven, though only by eight tenths of a decibel over “Sludge Puppy”. In this genre that reading is a compliment before it is a complaint, because a riff that refuses to resolve for six minutes is the whole point of sludge. The question is whether it earns the length, and on a record where the four middle tracks already measure alike, it is the one that asks the most of a first listen.
What the master gets right
Peak to average runs between thirteen and two tenths and fourteen and seven tenths across all seven tracks, and the average level sits between minus fourteen and minus fifteen and seven tenths. Nothing here was pushed to get loud.
That matters more in sludge than in most genres, because the temptation is to bury the whole band in one saturated block and call the mud a texture. Castle keeps the peaks. The low end has room and so do the cymbals. “Cyclone” carries the most treble on the album at twenty four and four tenths percent against sixteen and one tenth on “Wild Bill”, and neither of them sounds thin or buried.
What sixty percent at one level costs
Four out of five. The playing is solid, the master is honest in a genre where it often is not, and the wide opener and the two tracks at the end show somebody thought about the running order rather than dumping seven songs in recording sequence.
The reservation is what it costs to plant your feet for sixty percent of a record. The four tracks on the plateau are not interchangeable, and the measurement says so clearly: “Employee Of The Month” runs over forty percent longer than “Wild Bill”, and across the four the spectral centre spans five hundred and twenty Hertz while the energy below 250 Hz spans almost nine points. What they share is the one axis a listener notices first, how hard the band is pushing, and holding that steady across four songs asks the riffs to carry the difference on their own. On a first pass through Castle they mostly do and occasionally do not.
Go to “Castle” and then “Wastland”. Those two are the widest things here, and the four flat ones between them are the part you grow into.
The treble swings by half again across the record. “Wild Bill” puts sixteen and one tenth percent of its energy above 5 kHz and “Cyclone” puts twenty four and four tenths, the lowest and the highest of the seven.
The last two pieces are where the master lets go. “Cyclone” is the quietest thing here on average level, and “Wastland” keeps more room above its own average than anything else on the album.
Across all seven the average level tops out at minus fourteen, on “Employee Of The Month”, and falls away to minus fifteen and seven tenths on “Cyclone”. The bottom end keeps its space and so do the cymbals, which on a sludge record is a decision rather than a default.
