Five Iron Frenzy's last album, Engine of a Million Plots, (Spotify) is an extremely good, mature rock album, the best yet after a 10-year hiatus. Their singer has one of my favorite voices. It feels like it came out last week, and I've listened to it hundreds of times. They're making another album, and here's the kickstarter.
I've also returned again and again to Lo Tom's first album (Spotify); it moves steadily forward the whole time, unassuming but intent, and loops easily. They're also kickstarting their next album.
I try to link to Bandcamp when I can, but neither of these earlier records is on there. Oh well!
