Massive Attack - Protection

Would've voted for 'Karmacoma', I think, but I haven't heard this album in like 15 years.

does anyone know the story behind Vivien Goldman's writing credit on "Sly"?

From this piece by Goldman:

Years later, after the band had released Blue Lines and were preparing the album that became Protection, I visited Bristol to collaborate with them, eventually co-writing the track "Sly." Sample-based songwriting in those pre-digital days could be laborious. I bought a child's Casio keyboard to help fill the gaps, which came in handy for "Sly," but the process often involved someone getting on their bike and cycling down to the second-hand record shop to try and locate half-remembered grooves that might be just right to fulfill the elusive conception of a song.
