Olivia Tremor Control is one of the most tantalizing acts I've heard. They came up with hooks effortlessly, but would often undermine any possibility of radio play with instrumental chaos within their catchiest songs (such as the woodwind chaos at the end of A Peculiar Noise Called Train Director and the use of a musical saw in the middle of I Have Been Floated). This is a good reflection of the creative dichotomy between Bill Doss, the more traditional pop leaning songwriter, and the more experimental Will Cullen Hart.
The other thing is they didn't really have that many traditional songs. Their albums were loaded with sound collages and one has to hunt through them to find the actual "songs". Once you find them, it's quite rewarding. My personal favorite might be No Growing (Exegesis). This is admittedly not unusual for Elephant 6 bands, among which Olivia Tremor Control was the most accessible. I'd argue that the Apples in Stereo, easily the most "polished" of the Elephant 6 group, most approximate what OTC could have been.
Hart continued on after Doss's death, but with Hart's unexpected passing in 2024, we've likely heard the last of OTC, though the band still at least still exists in name.
