Regarding jazz 2018 has been the best year since Coltrane died
86-87 were two of the most incredible back to back years in the 20th C
For 2018 the pace of incredible releases made it hard to revisit many of them because they kept pouring in but still 2016 was zenith year or whatever. Many things hit a sweet spot in 2016. For pop music or avant pop or whatever 2016 was the best year since 86.
