This three way split CD, featuring Watership Down, LIGHT and Chalkline came out on Primrose Records in 1997. If you've never heard this split, you might remember Watership Down from their 7" on Immigrant Sun, and Chalkline from their releases on Shandle Records. Although I don't have a copy, it appears that LIGHT also released a CD on Uprising Records.
