When is a CD a bargain? In those rare instances when two albumsare reissued on one disc, taking advantage of the format’s 70-minutecapacity. Just check out these twofers:1.Captain Beefheart The Spotlight Kid/Clear Spot (Warner Bros.)Two peaks from an authentic cult weirdo who makes Zappa seem normal.2.Gram Parsons GP/Grievous Angel (Warner Bros.) From-the-soulcountry rock by the man who invented it.3.Big Star 1 Record/Radio City (Stax) Two critically reveredfaves by Alex Chilton’s cult ’70s band.4.Beach Boys Smiley Smile/Wild Honey (Capitol) Quirky mid-’60snuggets like ”Good Vibrations.”5.X Los Angeles/Wild Gift (Slash) The white-heat scorch of thebest of L.A. punk.6.R.E.M. Dead Letter Office/Chronic Town (I.R.S.) An album offor-fans oddities, plus their first EP.7.Howlin’ Wolf Moanin’ in the Moonlight/Howlin’ Wolf (Chess/MCA)Because we can never get enough of Wolf’s death-rattle voice.8.Ramones All the Stuff (and More) Vol. 2 (Rocket to Russia/Roadto Ruin) (Sire) Their third and fourth LPs are a nonstop punk blast.

9.Muddy Waters Sings Big Bill Broonzy/Folk Singer (Chess/MCA) Nothis greatest hits, but the true roots of blues.10. Johnny Cash At Folsom Prison and San Quentin (Columbia) TheMan in Black behind bars, and never more ornery.
