Finally open and well on its way to earning a rep as one of the best live music rooms in Chicago, the new Bottom Lounge, 1375 W Lake St, hosts two strong shows this weekend. Tonight, a killer quadruple bill starts at 8 tonight and features the breathtakingly beautiful local ork-pop ensemble the Chamber Strings and the consistently inventive singer and songwriter David Singer, as well as La Scala and Penthouse Sweets; tickets are $8 in advance or $10 at the door. On Saturday at 8, Sufrajett and Lonesome Cougar open for ’90s alternative rock heroes Urge Overkill; those tickets are $16 in advance or $20 at the door.

If the Old Town School of Folk Music’s Folk & Roots Festival still hasn’t satisfied your craving for those sounds, Charter One Pavilion on Northerly Island presents the strong double bill of soul legend Al Green, supporting his strong new album “Lay It Down,” and New Orleans shaman Dr. John, with Soulive opening starting at 6 p.m. Tickets are $35 to $85 through www.ticketmaster.com or (312) 559-1212.
