man
he's mumbling/slurring and half the time fades out of the mic etc.
it's punk rock yo! like i guess i could understand a complaint about vocal acuity if it were consistent with the music you listen to, but there are enough poor/obnoxious vocalists in the bands you listed that i don't think your problem with the clash's vocals makes much sense! also honestly strummer has a great fucking voice and i would not consider it MUMBLING so much as YELLING and/or the product of a fairly strong accent. the dirtiness/sloppiness is very much a part of the punk rock attitude and sound (although the clash was an insanely tight band) and this is something i appreciate quite a lot about strummer's vocals. i guess you are used to some POST GRUNGE shit that has watered down its punk rock influences to such an extreme degree that the clash sounds somehow outside your comfort zone, but honestly besides being composed entirely of EXTREMELY GOOD TRACKS London Calling in particular is an extremely accessible album. i always kind of thought it was one of the records basically anyone raised in a Western musical culture could listen to and immediately appreciate if only for its hooks/sound/performance but i guess not and i don't know what to tell you man!
