Sort of tangent from the controversial opinions thread but spells of a few years where an artist releases loads and it’s all brilliant
MF DOOM 2003-2005 is the obvious one for me
Take me to your leader
Vaudeville villain
Madvillainy
Venomous Villain
Mm… Food
Mm… Leftovers
The mouse and the mask
Plus all the metal fingers beats boxsets
In under 3 years. Ridiculous
Dylan’s hard to beat:
The Freewheelin’ Bob Dylan
The Times They Are a-Changing
Another Side of Bob Dylan
Bringing it All Back Home
Highway 61 Revisited
Blonde on Blonde
All within the space of 3 years.
Miles Davis 1957-1960 (Birth of the Cool, Miles Ahead, Milestones, Porgy and Bess, Kind of Blue, Sketches of Spain)
Sadness 2017-2019 (Leave, Tundra, Rain, Somewhere Along Our Memory, Circle of Veins, I Want to Be There, loads of singles)
Possibly cheating but Timbaland’s production in the late 90s/early 2000s and the Wu-Tang Clan from 1993 to 1996 if you include the solo albums are also pretty untouchable.
I’ll allow production hot streaks
Chuck Schuldiner (Death) has a streak which went through his whole career tbf. If i was being picky Spiritual Healing may be a blip but really…
Scream Bloody Gore
Leprosy
Spiritual Healing
Human
Individual Thought Patterns
Symbolic
Sound of Perseverance
are all stellar albums
Al Jourgensen’s mid 80s to early 90s period for me…
Twitch - Ministry (1986)
Big Sexy Land - Revolting Cocks (1986)
The Land Of Rape & Honey - Ministry (1988)
The Mind Is A Terrible thing To Taste - Ministry (1989)

The Last Temptation Of Reid - Lard (1990)
Psalm 69 - Ministry (1992)

Plus just having some spare songs knocking around to release via Pailhead and 1000 Homo DJs 
Pet Shop Boys’ Imperial Phase
Help, Rubber Soul, Revolver, Sgt Pepper, White Album. 3 years
Guided By Voices mid 90s run is as good as indie rock ever got
Propeller (1992)
Vampire on Titus (1993)
Bee Thousand (1994)
Alien Lanes (1995)
Under the Bushes, Under the Stars (1996)
Not in My Airforce (1996, Bob’s solo debut)
Carnival Boy (1996, Tobin’s solo debut)
plus Tonics & Twisted Chasers and Sunfish Holy Breakfast in 96 for good measure
And Magical Mystery Tour ep/album.
I was thinking about Bob’s 96-99 run…
UTBUTS
Tonics
Sunfish
Mag Earwhig
Do The Collapse
Airforce
Waved Out
Kid Marine
Speak Kindly
Animal Collective’s famous run of glory in the 00s:
Neil Young 1969-1975:
S/T
Everybody knows…
After the gold rush
Harvest
On the beach
Tonight’s the night
Zuma
New Order 1982 to '86 is pretty hard to top. A run of singles including Temptation, Blue Monday, Thieves Like Us and Bizarre Love Triangle, and three 10/10 albums in Power, Corruption & Lies, Low-Life and Brotherhood.
1982-1988
1999

‘Heroes’
& co-producing/co-writing - The Idiot, Lust for Life & Transformer
What’s Going On, Trouble Man, Let’s Get It On and Diana & Marvin (71-73)
I had no idea DOOM and Dylan had produced those streaks within only 3 years each, that’s mind boggling. Especially for MF DOOM, I can’t get my head around it.
Love that he released nothing in the 3 years before or 4 years after that run too.
Just 3 years of nonstop writing incredible beats and bars then fuck immediately back off
Here Come The Warm Jets, Taking Tiger Mountain, Another Green World, Discreet Music (74-75)
Not satisfied with his weird pop stuff Eno decides to just invent ambient lol
