If you are a classic rock fan then this debut album should be in your collection.  In my opinion it doesn't get any better for this band that this album.  Bad Company, another Super Group, with members from the band Free, King Crimson & Mott the Hoople, was the first release of Swan Song Records (Zeppelins label).  With this album going 5 times platinum (5 million +) it should be fairly easy to find a good quality copy floating around out there.  I don't think there is a bad song on this album, and certainly some great hits like the title track.  Considered a hard rock band this album isn't a head banger by any means. Consider The Way I Choose  :

From Hard Rock we go to Folk. Joan Baez on her debut self titled album on the Vanguard label, released in 1960 shortly after playing at the Newport Folk Festival in '59.  Consisting of folk and traditional ballads, some from centuries back, this is a great folk album. Simple with just acoustic guitar and beautiful vocals.
This copy, although an original Canadian pressing, is in kind of rough shape, lots of pops and tics but fortunately no skipping.

Her 10th studio album One Day at a Time has her singing the Jagger/Richards song No Expectations, the Wilkin/Dill  song made famous by Johnny Cash Long Black Veil, as will as two of her own compositions Sweet Sir Galahad and A Song for David.  This album has a more country folk feel that her first and is accompanied by a host of musicians.  Vanguard VSD 79310.

Ok, with a cover like this and songs such as Portuguese Washerwoman and Gay Ranchero, how could I resist!  Formed in 1964 by Herb Alpert to capitalize on the popularity of the Tijuana sound, this band actually out lasted the Tujuana Brass.  Go figure! This is the 4th studio album from 1966 on A&M Records LP 118, and it sounds like you may expect - marimba music with guitar, brass, reed and percussion. Couple shots of tequila along with this album and you are in Mexico!  Second hand store purchase, probably a buck or less.
