After a trip to the US to promote The Man Who Sold The World, Bowie returned with a whole new perspective on songwriting, as well as a new band and a new record label.  From these changes came his
fourth studio release, and his first album with RCA, Hunky Dory. This is an excellent album and a must have for any Bowie fan; it is the beginning of his music as we know it.  Here is the song Kooks, as the album notes
"(for small  Z)", his new son Zowie; followed by another of my favourites from this album Queen Bitch. (remind you of Velvet Underground?)

Considered one of the best Rock & Roll albums of all time, it is hard to pick favourites from this iconic album.  Released in 1972 on RCA LSP 4702, The Rise And Fall of Ziggy Stardust And The Spiders From Mars, is a concept album originally intended by Bowie to be a soundtrack to a stage or TV production.  This was the beginning of Bowie Mania! No longer a pop star, now a super star. Kids everywhere were dressing like Ziggy.
Here is the title track and then Rock 'n' Roll Suicide

Bowie's '73 release was somewhat influenced by his half brothers recent diagnosis of schizophrenia. The lightening bolt signifying a split personality and the word play title Aladdin Sane (A Lad Insane). Another great album with the huge hit The Jean Genie, as well as Panic in Detroit, Cracked Actor and Watch That Man. My copy of this album is kind of rough, so will eventually be replaced by a better copy.
Here is the flamenco flavoured  Lady Grinning Soul:
