The songs on Solitude Standing, Suzanne Vega's second album, had years listed beside them on the lyric sheet, so you could see that some of them dated back to 1978. But that bold admission heralded the album's triumph – its diversity was what made it so good. Partially, that was because the old songs were the equal of anything on the first album – tunes like the a cappella slice-of-life "Tom's Diner" and the warmly romantic "Gypsy" simply wouldn't have fit thematically on the debut. On Solitude Standing, however, they became part of an album of story songs set in a variety of musical contexts; many had band arrangements, and in fact, members of Vega's touring band often were credited as co-writers. Additionally, Vega had developed more as a singer without losing the focused intonation that had made her debut – one of many compelling elements which helped make "Luka," a character song about domestic abuse, a fluke hit.

As an Australian, guitar virtuoso Tommy Emmanuel doesn't seem to be much bothered about musical categories. Is his music jazz, folk, bluegrass, new age? Depending on the track, it can be any one. Like his mentor, Chet Atkins, Emmanuel is simply a guitar player, and on Little by Little, a two-CD set, he sticks mostly to acoustic guitar, playing mostly originals, tunes that he has used in concert but not recorded before. He is also mostly solo, although the double-disc length allows him room to share space with guests including singers Pam Rose (on her co-composition "Haba Na Hava") and Anthony Snape (on the folk-rock "Willie's Shades"). Among the covers are two versions of "Moon River," one with a bass countermelody, the other with an Emmanuel vocal, Carole King's "Tapestry," Atkins' "Mountains of Illinois," and "The Tennessee Waltz." Emmanuel plays fast runs, slows down for delicate passages, and adds harmonics on tunes that evoke players including Will Ackerman and John Fahey. He also likes folk-pop; "Papa George" needs only a James Taylor vocal to fit into that category. But Little by Little is a tour de force by a musician who usually leaves categories behind.

None of the Band's previous work gave much of a clue about how they would sound when they released their first album in July 1968. As it was, Music from Big Pink came as a surprise. At first blush, the group seemed to affect the sound of a loose jam session, alternating emphasis on different instruments, while the lead and harmony vocals passed back and forth as if the singers were making up their blend on the spot. In retrospect, especially as the lyrics sank in, the arrangements seemed far more considered and crafted to support a group of songs that took family, faith, and rural life as their subjects and proceeded to imbue their values with uncertainty.

The Band's first album, Music from Big Pink, seemed to come out of nowhere, with its ramshackle musical blend and songs of rural tragedy. The Band, the group's second album, was a more deliberate and even more accomplished effort, partially because the players had become a more cohesive unit, and partially because guitarist Robbie Robertson had taken over the songwriting, writing or co-writing all 12 songs. Though a Canadian, Robertson focused on a series of American archetypes from the union worker in "King Harvest (Has Surely Come)" and the retired sailor in "Rockin' Chair" to, most famously, the Confederate Civil War observer Virgil Cane in "The Night They Drove Old Dixie Down."

On Parenthesis, I, Josienne Clarke has not only embraced her past but has also redefined herself in the present, presenting a body of work that is shimmering, warm, intimate, and at times, profoundly heart-wrenching. Throughout her career, Clarke has been both a Rough Trade-signed artist and a BBC Radio 2 Folk Award-winner, two opposing poles that neatly sum up her inability to be pigeonholed. Parenthesis, I is a masterful journey through her personal and musical evolution, drawing influence from folk greats Nick Drake and Sandy Denny, as well as more contemporary artists like Julia Jacklin, Courtney Marie Andrews, Anaïs Mitchell and Lucy Dacus.

This 45-song, two-disc collection is subtitled "two decades of killer fretwork", and never was a set so aptly described. Chess Records was the home to seemingly every hot guitar player in the Chicago area, and many of them make their appearance here. Besides the usual label guitar hotshots (Muddy Waters, Jimmy Rogers, Chuck Berry, Bo Diddley, Buddy Guy, Lowell Fulson, Earl Hooker, Otis Rush, Robert Nighthawk, Little Milton), space is given to sideman work from legends like Hubert Sumlin and Robert Jr. Lockwood and great one-offs by lesser-known artists like Jody Williams, Danny Overbea, Eddie Burns, Joe Hill Louis, Morris Pejoe, Lafayette Thomas and others. It seems as if everyone recorded for Chess at one time or another, also explaining the inclusion of tracks by John Lee Hooker, Albert King, Clarence "Gatemouth" Brown, Lonnie Brooks, Hound Dog Taylor and Elmore James. If electric blues guitar's your thing, then look no further than this fine two-disc compilation.

Following the success of Sundown, Gordon Lightfoot continued his success by releasing a greatest-hits compilation. A double album (now a single CD), it contained the most popular songs from his Warner Bros. years on disc two, and he re-recorded many of his early songs for side one of record one. Although not as good, perhaps, as the originals, this did bring them up to date with his current sound style. Just about all the favorites are here (except "The Wreck of the Edmund Fitzgerald," which hadn't been recorded yet when this set was put together and appears on Lightfoot's second volume of Gord's Gold), making this a good general overview of a strong talent. When Warner transferred the double LP to CD, "Affair on 8th Avenue" was dropped from the program to make the set fit on a single disc. Randy Newman arranged the orchestration on "Minstrel of the Dawn," by the way.
