Lobos were somewhat vexed by La Bamba--it got them a lot of exposure, but to a lot of people it was the only song they were known for. Which reminds me--I've been meaning to post, over in the Concerts thread, about the Lobos show I saw at the Fillmore a couple weeks back. Very fab indeed--it was essentially their Kiko album, front to back, with a couple of encores thrown in.
They appeared, rather unexpectedly, on a Virgin Recommends compilation last year, with a song called "Rita." I loved it; never would have known it was them. Is that more or less how they're sounding these days?
Afraid I don't know the song, so I can't say for sure. For a time, they seem to have taken on the guise of a jam band, covering all sorts of 60s artists (Marvin Gaye, the Allman Brothers, Traffic, the Dead, Hendrix, Neil Young, Cream, to name a few) and really stretched out on these songs. While they still like to jam a bit, they seem to have gone back to playing more of their own material live. Also, they've added a couple of percussionists over the years, so that their original drummer Louie Perez, is now more a third guitarist than a drummer.
I'll see if I can find that song and let you know how typical of their current sound it is.
