This winter comiket CD is actually a bit of a compilation. Most notably, it features 「とろみかん 果汁0%」, a short-lived single that came out at M3-24. Then, from what I can gather out of the posted album cover, it also includes some (hopefully remixed versions of) songs from her 2006 mini-album 「たちつてとろ美ちゃん Ver1.2」. The rest are probably new. Of note, track number 3 "plus one" has English lyrics, though you couldn't tell from listening to the song (no offense torobaby).
Remember the estrogen-fueled denpa compilation "【電波系】作業用A - POP【痛サウンド】"? Toromi had a track on there and uploaded a nice promotional video for all to see.
She also appears in two of the most recent CRAZY OTAKU WORLD of GENKAN MATT videos.
