Question: Gregg Rolie and Rob Tyner, are a keyboardist?
Context: Abraxas Pool is a 1997 album by ex-Santana members Mike Shrieve, Neal Schon, Gregg Rolie, José "Chepito" Areas, Alphonso Johnson, and Mike Carabello. Robert W. Derminer (December 12, 1944 – September 18, 1991), known as Rob Tyner, was an American musician best known as lead singer for the Detroit proto-punk band, MC5.  His adopted surname was in tribute to the jazz pianist McCoy Tyner.  It was Tyner who issued the rallying cry of "kick out the jams, motherfuckers" at the MC5's live concerts.  Tyner had originally auditioned as the bass player, but the band felt his talents would be best used as a lead vocalist. José Octavio "Chepito" Areas (born 25 July 1946) is a Nicaraguan percussionist best known for having played timbales in the Latin rock group Santana from 1969-1977 and 1987-1989.  In 1998, he was inducted into the Rock & Roll Hall of Fame for his work in Santana.  In 1997, he performed on "Abraxas Pool" with other members of the early 1970s iteration of Santana, including Gregg Rolie, Neal Schon, Michael Carabello and Michael Shrieve.  Previously, he released an eponymous solo album on Columbia/CBS Records in 1974.  "La Gigantona", a 1976 collaboration with Nicaraguan singer-songwriter and childhood friend Alfonso Noel Lovo, was reissued by Numero Group in 2012.  Featured along with Richard Bean in "The Sounds of Santana" CD by Mike Roman & The Tellstars (2003).  Featured along with Michael Shrieve in "Cha Cha Time!"  CD by Mike Roman & The Tellstars (2007). Gregg Alan Rolie (born June 17, 1947, Seattle, Washington, United States) is an American singer and keyboardist.  Rolie served as lead singer of the bands Santana, Journey and Abraxas Pool – all of which he co-founded.  He also helmed rock group The Storm, and currently performs with his Gregg Rolie Band.  Rolie is a two-time inductee of the Rock and Roll Hall of Fame, having been inducted both as a member of Santana in 1998 and as a member of Journey in 2017. The Departure Tour was a concert tour by the American rock band Journey.  The tour was in support of their 1980 album "Departure" which was their first Top 10 album on the "Billboard" 200 that peaked at #8 and like their previous two albums, "Infinity" and "Evolution".  This was also the last Journey tour to feature founding member of the band Gregg Rolie who left the band to start a family. Caravanserai is the fourth studio album by Santana, released on October 11, 1972.  It marked a major turning point in Carlos Santana's career as it was a sharp departure from his critically acclaimed first three albums.  Original bass guitarist David Brown left the group in 1971 and was replaced by Doug Rauch and Tom Rutley, while original percussionist Michael Carabello left and was replaced by Armando Peraza.  Keyboardist/vocalist Gregg Rolie, who was having a falling-out with Santana, was replaced by Tom Coster on a few songs.  "Caravanserai" reached number eight in the "Billboard" 200 chart and number six in the R&B Albums chart in 1972. "No One to Depend On" is a song by Latin rock band Santana, from their 1971 album, "Santana III".  It is the second track on the first side of the LP album and was released as its second single.  It was written by Mike Carabello, Coke Escovedo, and Gregg Rolie. "Black Magic Woman" is a song written by Peter Green that first appeared as a Fleetwood Mac single in various countries in 1968, subsequently appearing on the 1969 Fleetwood Mac compilation albums "English Rose" (US) and "The Pious Bird of Good Omen" (UK), as well as "Vintage Years".  In 1970, it became a hit by Santana, as sung by Gregg Rolie, reaching No. 4 in the U.S. and Canadian charts, after appearing on their "Abraxas" album.  In 2005 the song was covered by ex-Thin Lizzy guitarist Snowy White on his album "The Way It Is".  In 1996, the song was also covered by Gary Hoey on his album "Bug Alley". "I Wanna Go Back" is a 1984 song by American rock band Billy Satellite, written by band members Monty Byrom, Danny Chauncey, and Ira Walker, that achieved major popularity when recorded by Eddie Money in 1986.  Another version was recorded by former Santana/Journey keyboardist/singer Gregg Rolie for his self-titled 1985 debut solo album. Welcome is the fifth studio album by Santana, released in 1973.  It followed the jazz-fusion formula that the preceding "Caravanserai" had inaugurated, but with an expanded and different lineup this time.  Gregg Rolie had left the band along with Neal Schon to form Journey, and they were replaced by Tom Coster, Richard Kermode and Leon Thomas, along with guest John McLaughlin, who had collaborated with Carlos Santana on "Love Devotion Surrender".  "Welcome" also featured John Coltrane's widow, Alice, as a pianist on the album's opening track, "Going Home" and Flora Purim (the wife of Airto Moreira) on vocals.  This album was far more experimental than the first four albums, and "Welcome" did not produce any hit singles.
