Founded originally as Landslide Records by Matthew Brooks as a means to release music for his band Hunter. Needing capital to fund the label, he was issued a $6000 grant from New Hampshire Vocational Rehabilitation. Lansylde Records expanded to include bands of his friends.
The first of these bands was Killer Foxx whose members were recruited from an unnamed cover band. The second of these bands was Thrash Queen which came about as a means to bring female musicians into the scene. Of these two bands, Matthew Brooks wrote all the material for Killer Foxx while writing roughly half for Thrash Queen.
The label faced legal trouble following a notice for copyright infringement from Landslide Records, prompting Brooks to change the name to Lanslyde Records. Further trouble down the line came when the intended album cover for Killer Foxx featured a man and woman engaging in oral sex hence the original album title All You Can Eat. Eventually, the woman who issued the grant was, in Brooks's words, "banished to Siberia". The LP was later issued under the title The Night with modest cover art.
Ingo Nowotny of Metal Enterprises expressed an interest licensing and distributing Lanslyde Records's catalog. The Metal Enterprises editions were presumably mastered directly from the vinyl as Nowotny never asked Brooks for the master tapes.
The label then quietly folded before the end of the 1980s.
