I lost their track in early 90's
The 90s were not good for them, with albums of decreasing quality. However, they rose again like a phoenix in the 00s, when each album they released was better than the previous one.
Acción directa (2000) was a return to what they did best. Bésame (2002) was a continuation, but with a metal sound at times. Hombre mate hombre (2004), with a new drummer (Ibi Sagarna, now with Leize) is great too, and was followed by some great live albums (Latidos y Mordiscos; the former features a conventional live show - I was at the gig they recorded for the album and DVD - and the latter some superb acoustic versions of their songs) and a box set of rarities (25 años de rocanrol https://es.m.wikipedia.org/wiki/25_años_de_rocanrol).
La tierra está sorda (2009), their concept album about the fascist repression during the dictatorship that followed the Spanish Civil War (based on true stories) is a masterpiece.
If you like the band, you will probably enjoy those albums.
