rivermaya now has more brit-rock influnences, lots of sound layers in their songs
the older rivermaya was a bit different, more straightforward but catchy. but it had more elaborate guitar techniques due to perf de castro's skills. i think that's the reason bat umalis si perf, he's more inclined to the hard rock, rock n roll genre, and rico was more into the indie-alt-pop genre
and for those who didnt know, bamboo didnt write the old rivermaya songs, he just sang it. it was still rico who wrote most of them
