try Kiwi Jr. - Cooler Returns, Alvvays - Blue Rev, The Beths - Future Me Hates Me, The Beths - Expert in a Dying Field, Ducks Ltd. - Modern Fiction, LVL UP - Hoodwink’d, Ovlov - Buds, Ratboys - Printer’s Devil, Wallows - Nothing Happens
None of those are from this year, but are all mostly recent. Not many bands are really doing “straightforward indie rock” nowadays but those come close.
Lots of excellent suggestions here already but I would add If you enjoy Wednesday, make sure to check out their guitarist MJ Lenderman - Boat Songs. Also Momma - Household Name. The band Rolling Blackout C.F. Has released 3 solid albums.
