You name some very good artists as well as some unfamiliar to me because I am as old as rock-n-roll. You cannot go wrong with anything below. Trust me on this
In know particular order: (except for the Clash, who earned their spot at the top)
The Clash--Get either the UK (import in USA) release "The Clash" or the triple-record "Sandinista!", the first so as to remember the seventies as the wake for the sixties and the approaching skeletal scariness of Ronald Raygun, and "Sandinista!" for the six sides which distill rock, folk, rap, skiffle, gospel, dub, dance, and ambiance into a rich liquor for the soul. Then get everything else.
The Psychedelic Furs--One of the most under-rated combos ever. Richard Butler knows about words. Word. Some bands know what electric guitars are for, and the Furs sure do. Get the first album, the eponymous one with "India" and "We Love You" and "Imitation of Christ". Since you got that one, you might as well get "Talk Talk Talk" (never to be confused with a band called TalkTalk)--it has a great love song called "Into You Like a Train" plus the widely-overlooked "Colors"--I think that's the name (I can't find my records!)-- "Listen to the weatherman, he's not saying anything..." Apparently Richard and bass-playing brother Tim were kind of weaned on Dylan by their Bobolicious father.
Chuck Berry--Everyone must get some Chuck--He is, you see, THE KING of rock-n-roll, not Elvis, oh-no-no. Elvis was a great singer and dancer, but he didn't write even his OWN songs. No, give it up for Chuck Berry. All the music you and Eye like owes a great debt to Berry, Fats Domino, Bill Haley, Buddy Holly, Bo Diddley.
Get aBUNCH of ska records!! Have FUN--Specials, Desmond Dekker, Bad Manners, Selecter, the Beat, Madddnesss. Dance a lot
Get "Songs of Love and Hate" by Leonard Cohen--breathe words like air and life and love and fire
You have to get a lot of Bob Dylan. You just have to. Everybody does. Get "Blond on Blond" of course for sure, hear "Sad-eyed Lady of the Lowlands" and "4th Time Around" and "Temporary Like Achilles" and "Visions of Johanna" and everything else except maybe "Obviously Five Believers"<
Get James Brown's "Twenty Fabulous Hits" or the "Live at the Apollo" album. Dance in Heaven, Godfather
James Brown,The Jam, X, the Buffalo Springfield, Trial by Fury, Tom Waits, Bob Marley, REM, Stones, Ramones, The Who--don't forget the Who, the Doors and on and on...keep your ears peeled--there is always something good coming along....
Plus get a thousand other albums....oh, yeah, get "Blue" by Joni Mitchell. If you don't like it (but you will) donate to a group for young songwriters.
