Welcome to The Weekend Stream, a relaxing weekly review of notable digital-only catalogue titles. There may be no CD or vinyl, but there's plenty of great new/old music to discover! A short but sweet week offers remixes of a disco legend, demos from a rock icon and more.

Lou Reed, I'm So Free: The 1971 RCA Demos (RCA/Legacy) (iTunes / Amazon)

Released for Record Store Day this past spring - and ahead of an earlier set of demos coming from Light in the Attic next month - this collection of material from Lou Reed's first solo studio session for RCA includes early versions of tracks that would end up on his first four studio albums, including "Berlin," "Wild Child" and "Perfect Day."

Donna Summer, Love to Love You Donna (Deluxe Edition) (Verve/UMe) (iTunes / Amazon)

This 2013 collection featured new remixes of Donna Summer classics by an impressive crop of dance producers including Frankie Knuckles, Hot Chip, Chromeo, Masters At Work and the late disco queen's collaborator Giorgio Moroder. An additional four mixes are featured on this digital deluxe edition, back in "print" after an absence.

Roger Miller, Supersongs (Columbia) (iTunes / Amazon)

Following last week's delivery of Miller's first Columbia album (released right after his best-known work with Smash Records), Legacy now brings in his second and final album for the label, originally shipped in 1975. It features the singles "Our Love" and "I Love a Rodeo," neither of which made the country Top 40.

Guy, Wanna Get with U EP / D-O-G Me Out EP (MCA/UMG)

Get with U: iTunes / Amazon
D-O-G: iTunes / Amazon

New York trio Guy helped usher in the new jack swing sound with their 1988 self-titled debut - but by second album The Future they were nearly on the skids: Co-founder/producer Teddy Riley assumed a chunk of vocal duties in place of Aaron Hall. But even with sales being half of its predecessor, the album spun off a quartet of Top 10 R&B hits, including "Wanna Get with U" and "D-O-G Me Out." These EPs include rare remixes that were previously included on a digital deluxe edition of the album from earlier this year.
