So, beyond the stuff I mentioned earlier...
Teeth of the Sea - very nice indeed! Primarily instrumental post-rock with more trumpet than expected.
The Claypool Lennon Delirium - bloody weirdos!
@Mickdundee's description above is pretty accurate but I think this is quite commercially viable.
James Yorkston - probably his least folk album yet. Some lovely ballads, some spoken word over interesting tunes type stuff.
3x4 - 80s LA slightly psychedelic rock bands covering other 80s LA slightly psychedelic rock bands. Has its ups and downs. The Bangles are the best known band on there, Dream Syndicate probably the best.
Julia Jacklin - enjoyable! More laidback than her debut was or, indeed, the Phantastic Ferniture album was.
du Blonde - better than I expected based on the reviews. Essentially grungey pop with psychedelic and folk influences.
Martin Frawley - Former singer of Aussie band Twerps. This is an excellent example of the Antipodean indie album. Reminds me a lot of The Chills and, to a degree, The Go Betweens.
Sleaford Mods - decent enough. Sounds like nobody much else. Not sure they're evolving massively.
Murray A Lightburn - literate indie rock. A bit less guitarish than his work with The Dears. A solid 7.5/10 type album.
Our Native Daughters - folk/Americana, quite marvellous! As I mentioned, a bit of an all female banjo supergroup. Songs are blooming excellent as are the voices, harmonies etc.
