Question: Which band, Letters to Cleo or Screaming Trees, had more members?

Passages:
Letters to Cleo are an alternative rock band from Boston, Massachusetts, best known for the 1994 single, "Here & Now", from their full-length debut album, "Aurora Gory Alice".  The band's members are Kay Hanley, Greg McKenna, Michael Eisenstein, Stacy Jones, Scott Riebling, and later, Tom Polce. Truly is an American rock band formed in the wake of the grunge era.  It featured singer-guitarist Robert Roth, bassist Hiro Yamamoto, and drummer Mark Pickerel.  Yamamoto and Pickerel were founding members respectively of Soundgarden and Screaming Trees.  While not a commercially successful group like some of their Seattle contemporaries, the band lasted a decade with two studio albums to their name. Change Has Come was the only recording the Screaming Trees released through Sub Pop.  Released in 1990 the Screaming Trees then moved on to a major label, Epic Records, for their next three albums - "Uncle Anesthesia", "Sweet Oblivion," and "Dust", as well as the "Something About Today" EP. Jamboree is the second album by Beat Happening, released in 1988 through K Records/Rough Trade Records.  All songs were produced by Steve Fisk with assistance from Screaming Trees members Mark Lanegan and Gary Lee Conner (who plays a brief guitar solo on "Midnight a Go-Go"), except "Cat Walk," produced by Patrick Maley, and "The This Many Boyfriends Club," recorded live by Rich Jensen.  The album marks a darker approach to the Twee pop for which the band is known, due largely to a thicker production than is present on the group's earlier recordings and the dominance of tracks written by Calvin Johnson, while Heather Lewis only provides vocals on two songs, the uncharacteristically brash "In Between" and the more typically understated "Ask Me."  At the time of the album's release, Calvin described Jamboree's sound as "dark and sexy."  Still, the band retained their emphasis on exuberance over musicianship, as Bret Lunsford stated in an interview that, while recording album opener "Bewitched," his guitar string got stuck on a protruding screw and he continued to play through the song, hitting the string a bit harder until it became unstuck. <P1-S0> Gary Lee Conner (born Lee Gary Conner on August 22, 1962 in Fort Irwin, California, USA) was the lead guitarist for rock act Screaming Trees, along with his brother Van Conner, who was the band's bassist. <P1-S1>  Conner began his career with Screaming Trees in 1985 which lasted until their disbanding in 2000. <P1-S2>  During that time he released two non-Tree albums: The Purple Outside-Mystery Lane (1990 New Alliance Records) with brother Patrick Conner on Drums and the single Grasshopper's Daydream/Behind The Smile (1999 sub pop) this album also featured Josh Homme from Queens of the Stone Age. <P1-S3>  Appearances on other artists material include, Beat Happening "Indian Summer" and "Midnight a Go-Go" from "Jamboree" as well as "Against the 70s" by Mike Watt from "Ball-Hog or Tugboat? <P1-S4> " (1995 Columbia Records). <P1-S5>  After ten years of seclusion he finally released a new album in 2010 from his band Microdot Gnome. <P1-S6>  The album "4D Sugarcubes" was released on Moonbus International Recordings in April 2010 as was available on CD and MP3. <P1-S7>  At the moment he is planning future releases from Microdot Gnome. <P1-S8>  In August 2016, Conner released a long-awaited solo album, Ether Trippers, on Strange Earth Records. Mad Season was an American rock supergroup formed in Seattle, Washington in 1994 by members of three popular Seattle-based bands: Alice in Chains, Pearl Jam and Screaming Trees.  Mad Season released only one album, "Above", and is best known for the single "River of Deceit".  The band went on a semi-permanent hiatus in 1996 due to the band members' conflicting schedules and vocalist Layne Staley's problems with substance abuse.  Attempts were made in the late 1990s to revive the group without Staley; however, the band dissolved following the death of bassist John Baker Saunders in 1999.  Staley died three years later of a drug overdose.

Originally released on Homestead Records in 1988, it was later reissued as part of Beat Happening's box set "Crashing Through" in 2002.  The journal of Kurt Cobain contains a draft of a letter sent to Mark Lanegan, in which he described "Polly Pereguin" as his favorite pop song of the 1980s.
