Problem: Background: Philip Chapman Lesh (born March 15, 1940) is a musician and a founding member of the Grateful Dead, with whom he played bass guitar throughout their 30-year career. After the band's disbanding in 1995, Lesh continued the tradition of Grateful Dead family music with side project Phil Lesh and Friends, which paid homage to the Dead's music by playing their originals, common covers, and the songs of the members of his band. Lesh operates a music venue called Terrapin Crossroads. He scaled back his touring regimen in 2014 but continues to perform with Phil Lesh & Friends at select venues.
Context: Lesh was an innovator in the new role that the electric bass developed during the mid-1960s. Contemporaries such as Casady, Bruce, James Jamerson and Paul McCartney adopted a more melodic, contrapuntal approach to the instrument; before this, bass players in rock had generally played a conventional timekeeping role within the beat of the song, and within (or underpinning) the song's harmonic or chord structure. While not abandoning these aspects, Lesh took his own improvised excursions during a song or instrumental. This was a characteristic aspect of the so-called San Francisco Sound in the new rock music. In many Dead jams, Lesh's bass is, in essence, as much a lead instrument as Garcia's guitar. Lesh was not a prolific composer or singer with the Grateful Dead, although some of the songs he did contribute--"New Potato Caboose", "Box of Rain", "Unbroken Chain", and "Pride of Cucamonga"--are among the best-known in the band's repertoire. Lesh's high tenor voice contributed to the Grateful Dead's three-part harmony sections in their group vocals in the early days of the band, until he largely relinquished singing high parts to Donna Godchaux (and thence Brent Mydland and Vince Welnick) in 1976 due to vocal cord damage from improper singing technique. In 1985, he resumed singing lead vocals on select songs as a baritone. Throughout the Grateful Dead's career, his interest in avant-garde music remained a crucial influence on the group. In 1994, he was inducted into The Rock and Roll Hall of Fame as a member of the Grateful Dead.

IN: Pyle was born to William Clyde Pyle and Maria Taylor near Dana, Indiana, on August 3, 1900. After attending local schools, he joined the United States Navy Reserve during World War I at age 17. He served three months of active duty until the war ended, then finished his enlistment in the reserves and was discharged with the rank of Petty Officer Third Class. After the war Pyle attended Indiana University, editing the Indiana Daily Student newspaper and traveling to the Orient with his fraternity brothers of Sigma Alpha Epsilon.

In 1926, Pyle, tired of working at a desk, quit his job. Over the following two years he and his wife traveled over 9,000 miles across the United States in a Ford roadster. In 1928 he returned to The Washington Daily News, and for the following four years served as the country's first and best-known aviation columnist. As Amelia Earhart later said, "Any aviator who didn't know Pyle was a nobody." In 1932 Pyle once again became managing editor of The Washington Daily News. Two years later he took an extended vacation in California to recuperate from a severe bout of flu. Upon his return, to fill in for the paper's vacationing syndicated columnist Heywood Broun, he wrote a series of 11 columns about his stay in California and the people he had met there. The series proved unexpectedly popular with both readers and colleagues. G.B. ("Deac") Parker, editor-in-chief of the Scripps-Howard newspaper chain, said he had found in Pyle's vacation articles "a Mark Twain quality that knocked my eye out." In 1935 Pyle once again resigned his position as managing editor to accept an offer from the Scripps-Howard Alliance to write his own national column. Traveling the highways and back roads of the country and the Americas, he wrote about the unusual places and people he met. Selected columns were later published posthumously in Home Country (1947). Perpetually dissatisfied with his writing, Pyle suffered from bouts of deep depression. He continued his daily column until a few months after the United States entered World War II on December 8, 1941.

Was his column successful?

OUT: Selected columns were later published posthumously in Home Country (1947).

Background: Adrian Frederick "H" Smith (born 27 February 1957) is an English guitarist, best known as a member of Iron Maiden, for whom he writes songs and performs live backing vocals on some tracks. Smith grew up in Camden, London and became interested in rock music at 15. He soon formed a friendship with future Iron Maiden guitarist Dave Murray, who inspired him to take up the guitar. After leaving school at 16, he formed a band called Urchin, which he led until their demise in 1980.
Context: In 1999, Smith re-joined Iron Maiden, along with vocalist Bruce Dickinson, who commented, "When he left the band in 1990, I think everybody was a bit surprised at how much we missed him and certainly, I don't think anybody had realized how much the fans would miss him - big time. I wouldn't have rejoined Iron Maiden if he wasn't in the band. I just don't think it would have been complete without Adrian, and now, it's great having three guitarists." The band embarked on a short tour, after which the new line-up's first album, Brave New World, was recorded with producer Kevin Shirley and released in 2000. He remains in Iron Maiden, with whom he has released four further studio albums, 2003's Dance of Death, 2006's A Matter of Life and Death, 2010's The Final Frontier and 2015's The Book of Souls. Smith claims that his guitar playing improved after leaving the band in 1990, in particular while working with Roy Z, from whom he "learned a lot about picking" and became "more disciplined." Since returning to Iron Maiden, he has also continued experimenting with tuning (which he began doing in Psycho Motel), stating that he has used drop D tuning in live renditions of "Run to the Hills", "Wrathchild", "The Trooper" and "Hallowed Be Thy Name". Although Smith had previously been known to contribute shorter, more "commercial" tracks, since his return to the band he has penned many longer songs, beginning with "Paschendale" from Dance of Death. Smith performs lead guitar, bass and backing vocals on the album Awoken Broken by his collaborative studio project with Mikee Goodman of SikTh called Primal Rock Rebellion. The title was released on 27 February 2012, while one song, "I See Lights", was released as a free download on the project's official website on 2 January.
Question: What is the band doing now?
Answer:
2015's The Book of Souls.
