Those band members who were/are very important but are overlooked or underrated.
1 George Harrison - The Beatles
George Harrison was an English guitarist, singer, songwriter, and music and film producer who achieved international fame as the lead guitarist of the Beatles.
I do think more modern era fans and history buffs give George his rightful appreciation. - Billyv
George is my favorite guitarist of all time. - Pony
This was very true especially in The Beatles active years and in the 70s. Musicians knew, the other Beatles knew, mainstream fans not so much. - Billyv
2 Aleksander Lifeson - Rush
3 Richard Wright - Pink Floyd
Richard William "Rick" Wright was an English musician, composer, singer and songwriter. He was the main keyboardist and a backup vocalist for the psychedelic and progressive English rock band, Pink Floyd .
He really made Pink Floyd what it was and gets almost the least credit - GillisL
4 John Paul Jones - Led Zeppelin
John Baldwin, better known by his stage name John Paul Jones, is an English multi-instrumentalist, songwriter, composer, arranger and record producer.
5 Alex Van Halen - Van Halen
Alexander Arthur "Alex" Van Halen is a Dutch-born American musician, best known as the drummer and co-founder of the hard rock band Van Halen.
6 Jason Newsted - Metallica
Jason Curtis Newsted is an American metal musician, known for being the third bass guitarist with the band Metallica from November 1986 until his departure in January 2001, he was also a part of Voivod and Flotsam and Jetsam.
Jason Newsted was amazing in my opinion. The guy had a lot of potential and getting a part to be a member of Metallica is a dream come true. Unfortunately, the band members mostly treated him unfairly and he responded in the fairest, yet saddest way possible; quitting the band. Because he didn't get to write many songs, unlike Cliff Burton (RIP), his bass-playing skills were never truly played to his full potential (Although he wrote "Blackened", my favorite song in...And Justice for All and even then, his sound was muted). And alongside being a great bass player, his vocals are aggressive and brimming with attitude, something which gave Metallica concerts an edge on being among the greatest concerts ever played (Live Seattle 1989, enough said). If he was in Metallica by 1983, I think he could have been lead vocalist (James Hetfield is legendary, don't get me wrong), but that's just my opinion. - CrimsonShark
7 Ray Manzarek - The Doors
Raymond Daniel Manczarek, Jr., better known as Ray Manzarek, was an American musician, singer, producer, film director, and author.
I think The Doors were unique in that all three non-Morrison members could be considered the "unsung hero". But Ray's keys are what give them their sound--even moreso than Jim's voice. - PetSounds
Great choice and reasoning. Again, you pick with your head while I picked somewhat with my heart. - Billyv
He Was Also The Manager Of The Band X - BeatlesFan1964
8 Chad Smith - Red Hot Chili Peppers

13 John Deacon - Queen
John Richard Deacon is a retired English musician, best known as the bass guitarist for the rock band Queen.
Grossly underrated member of Queen. - bzsuzsi0128
Another one bites the dust and Under pressure bass lines are iconic and awesome.
Sure he is the number one.
14 John Densmore - The Doors
15 Kevin Moore - Dream Theater
He wrote a lot of the material on their first three albums. - IronSabbathPriest
16 Gene Clark - The Byrds
Harold Eugene "Gene" Clark was an American singer-songwriter and founding member of the folk rock band the Byrds.
McGuinn's 12-string Rickenbacker deservedly gets a ton of praise for their sound, but Gene Clark actually wrote the majority of their songs, and sang lead on many of them too. When that jerk David Crosby finally succeeded in chasing Gene out of the band, they were still good, but never quite the same.
17 Ringo Starr - The Beatles
Richard Starkey known professionally as Ringo Starr, is an English musician, singer, songwriter and actor who gained worldwide fame as the drummer for the Beatles.
18 Brian Jones - The Rolling Stones
Lewis Brian Hopkin Jones was an English musician, the founder and the original leader of the Rolling Stones.
19 Mick Fleetwood - Fleetwood Mac
He's the core - holds it all together. And his background enhancements are often subtle and overlooked. - Billyv

Great Drummer - waldo
22 Mick Ronson - David Bowie & The Spiders From Mars
23 Boz Boorer - Morrissey
