Don't call it a comeback. Mostly because Bristol's brightest aren't really back, that is, the new record doesn't have much to do with the same place they left off. After ten years, Portishead reappears not to cash in on their mighty trip-hop legacy but to open up a new edgier trajectory out of its ruins. Picked this CurrentTV clip up from Sasha Frere-Jones' New York blog. http://www.newyorker.com/online/blogs/sashafrerejones/
It's half an hour of Portishead doing all new material live, and it's even better than the album versions. Full band, two drummers, no mercy. whatever you wanna call their new sound, it's a new understanding of the literal spirit of r&b - rhythm and blues, ill kraut-tempered beats together with desolate torch songs. For a band that doesn't like to perform and comes together every decade to record, they could easily, if they wanted, be a pop powerhouse like that other something-head band.
