The 100th release on TCFSR Bandcamp is the 28th release by tourmaline hum, although it is five years since their last album 'system Imperfect' 
During this time the duo of Lone Cosmonaut and Dental Drill have each created a number of solo releases and contributed to a variety of other projects (and Dental Drill has taken on the day to day running of the TCFSR label) so the tracks for 'Invasive Species' were created intermittently between 2017 and 2021. Nonetheless the album demonstrates a thematic consistency. The album has a darker edge than most of tourmaline hum's previous work.
