Crosby, Stills, Nash and Young-Deja Vu (1970)

Crosby, Stills & Nash, along with Cream, share the honor of being the first supergroup in history, and they, in particular, are the greatest in folk rock and country rock. 

The legendary past of its members was impressive and groundbreaking. David Crosby came from one of the pioneering folk rock bands, The Byrds, while Stephen Stills came from another influential band of the genre, Buffalo Springfield, and finally, Graham Nash came from one of the giants of British pop and blues, The Hollies. In 1969, they achieved one of the greatest accomplishments with their first and astonishing album, considered a true classic of rock music. 

After that first album, the trio embarked on an epic tour, for which they recruited a backing band. On the advice of Atlantic Records, they were suggested Neil Young, Stills' former bandmate in Buffalo Springfield, a Canadian who was already achieving great success with his new band, Crazy Horse. 

Young finally accepted the challenge, but not before setting some conditions, including that this new position wouldn't prevent him from continuing his solo career. 

In August 1969, the entire band performed at the Woodstock festival, in a show divided into two parts. The first consisted of an acoustic set, and the second an electric one, where Young's visceral and raw guitar work provided the perfect counterpoint to the rich vocal harmonies of his three bandmates. 

The band's triumphant performance at Woodstock encouraged the label to release a subsequent album. Before that, the group received the Grammy Award for Best Group of 1969, and in mid-1970, after more than 800 hours of work, "Déjà Vu" was released. It contained an impressive collection of songs, beginning with "Woodstock", composed by Joni Mitchell, the controversial "Almost Cut My Hair", and the superb "Teach Your Children" and "Our House". These tracks, along with others from the first album's repertoire, became an explosive mix of guitar jams in their concerts, featuring their endless guitar solos. Some of these historic live sessions were recorded on the double live album "Four Way Street".

Wishbone Ash-Argus (1972)

With this album, Wishbone Ash reached their peak thanks to a simply fantastic work combining their folk and rock roots with progressive elements.

Here they continue to showcase their impressive guitar duality, in addition to creating sublime, highly addictive, and complex compositions.

Songs like the progressive folk track "Sometimes Word", the harmonica-infused "Blowin' Free", the impressive "Time Was", the emblematic "The King Will Come", and the epic "Warrior" are undoubtedly some of the British group's best contributions to rock music.

With this album (the band's third chronologically), Wishbone Ash became one of the leading acts of British progressive hard rock, while simultaneously solidifying a lineup (Andy Powell, Ted Turner, Martin Turner, and Steve Upton), that would bring them many years of glory and tremendous success around the world.

Al Kooper, Mike Bloomfield & Stephen Stills-Super session (1968)

This album is considered one of the best jam sessions ever recorded, perhaps the best, featuring three renowned musicians: Al Kooper, the keyboardist on Bob Dylan's famous "Like a Rolling Stone" and a member of bands like Blood, Sweat & Tears and The Blues Project; Mike Bloomfield, the legendary blues guitarist influenced by blues greats like Muddy Waters and Albert King, and a member of Electric Flag; and Stephen Stills, perhaps the best known of the three, a member of Buffalo Springfield and later part of the legendary supergroup Crosby, Stills, Nash & Young.

"Super Session" is a collection of superb blues tracks, such as the instrumental "Albert's Shuffel", where Al Kooper showcases his piano talent; the version of Curtis Mayfield's "Really", a soul song transformed into blues; and the jazzy "His Holy Modal Majesty", the perfect setting for the greatness of Mike Bloomfield and his guitar. Stephen Stills takes the reins on the album's second side, and together with Al Kooper, they deliver an excellent version of Bob Dylan's "It Takes a Lot to Laugh, It Takes a Train to Cry". The epic eleven-minute jam "Season of the Witch" is one of the album's highlights, while the blues classics "You Don't Love Me" and "Harvey's Tune" put the finishing touch on a live performance as brilliant as it is effective. 

In short, "Super Session" is the work of three geniuses in a spectacular jam session, and while the result might seem somewhat pretentious, it was also well-received by critics and audiences alike and hailed as a blues-rock masterpiece.

The Highwayman-The Highwayman (1987)
